From an article by Javier Hidalgo. I've been wanting to put these notions into words, but he does it quite well...
If you’re a libertarian, you should endorse open borders. Here’s why.
Libertarians
prize individual liberty. According to libertarians, we have rights to
associate with others as we see fit and engage in economic transactions
with them. These rights are constraints on state action. Libertarians
think it is unjust for states to infringe on individual rights even in
order to bring about socially beneficial outcomes. States certainly
can’t violate our rights to protect some of us from economic competition
or shield our cultures from change.
These commitments should
lead libertarians to oppose immigration restrictions. When states
restrict immigration, they stop you from associating with foreigners and
engaging in many mutually beneficial economic exchanges with them. Want
to hire an unauthorized immigrant? That’s illegal. Suppose you have an
uncle who wants to immigrate to your country, and you want to sponsor
him. The odds are that your uncle won’t be able to immigrate.
From
a libertarian perspective, it’s hard to justify this interference with
the rights and liberties of individuals. And libertarianism is
a cosmopolitan doctrine.
It says that foreigners have rights too. Immigration restrictions seem
to abridge the individual rights of both citizens and foreigners.
Some libertarians reject rights-talk. They use more utilitarian
reasoning to evaluate public policy. And these libertarians also have a
good reason to oppose at least actual immigration restrictions. The same
arguments that justify free trade apply to immigration. More
immigration increases the division of labor and immigrants
help generate more wealth.
If you factor in the benefits of more open borders to foreigners, it is
hard to think of a public policy that has a bigger payoff than more
immigration. When economists crunch the numbers, they conclude that the
benefits of open borders are
in the trillions of dollars.
Libertarians are okay with some kinds of exclusion. Take private
property. If a homeless person wants to sleep in your house, you are
within your rights to exclude him. Maybe we should understand a state’s
right to exclude in similar terms. Perhaps a state’s territory is the
collective property of its citizens and this is reason that states can
exclude foreigners. Does this idea make sense?
No. At least, not from a libertarian point of view. It is false that
the government or citizens collectively own all of the territory of the
United States. Instead, individuals own a large chunk of it. Suppose you
wanted to invite some foreigners to cross the border and live in your
house. The government will likely say no. That looks like a violation of
individual property rights. So, if individuals have rights to private
property, then we should reject the view that the United States is the
collective property of its government or citizens.
Maybe you’re
concerned that immigration will change the national culture in bad ways.
Immigrants bring new and occasionally upsetting cultural norms and
customs with them. But you lack a right to freeze cultural change.
Here’s something else that can cause cultural change: freedom of speech.
People use their rights to freedom of speech to persuade people to
adopt new cultural norms.
Sometime they succeed and these new norms can
be startling and upsetting. Nonetheless, libertarians would firmly
reject attempts to restrict freedom of speech to avert cultural change.
The same point applies to immigration. Sure, immigration brings about cultural change. Deal with it...
...let’s suppose that expanding immigration really is politically
infeasible. Here’s where another key libertarian commitment comes in.
Libertarians are
skeptical about state authority.
Many libertarians deny that we have duties to obey the law just because
it’s the law. Libertarians say that, if it is wrong for you or I to
coerce other people, then it is wrong for the state to do this too, and
other people are under no duty to assist states by obeying their
commands. When states restrict immigration, they don’t merely stop
people at the border. States also force
private citizens to refrain from hiring, transporting, and renting to unauthorized immigrants. States conscript private citizens in violating the rights of foreigners.
Here’s where libertarians have some practical advice to give:
break the law.
Ignore immigration laws that try to get you to help the government to
achieve its unjust ends. In this way, libertarians’ critique of
immigration restrictions matters practically. While open borders may be
infeasible, there is something that you as an individual can do: refuse
to be complicit in the injustice of immigration restrictions.

ADDENDUM:
OR, here's another excellent article...
https://www.theatlantic.com/business/archive/2015/10/get-rid-borders-completely/409501/
that posits the reasonable questions and makes the following rational points, among others...
What moral theory justifies using wire, wall, and weapon to
prevent people from moving to opportunity?
What moral theory justifies
using tools of exclusion to prevent people from exercising their right
to vote with their feet?
No standard moral framework, be
it utilitarian, libertarian, egalitarian, Rawlsian, Christian, or any
other well-developed perspective, regards people from foreign lands as
less entitled to exercise their rights—or as inherently possessing less
moral worth—than people lucky to have been born in the right place at
the right time. Nationalism, of course, discounts the rights, interests,
and moral value of “the Other," but this disposition is inconsistent
with our fundamental moral teachings and beliefs.
Freedom of movement is a basic human right.
Amen and amen.
If anyone who thinks there is some rational and moral grounds for criminalizing immigration, please begin by answering the questions in bold.
