“Open immigration” in the context of capitalism means open to non-criminals and open to non-jidhadists. It does not exclude screening for criminals (those who violate rights), those with contagious diseases, and terrorists.
This is how Yaron Brook and Craig Biddle use the term. (I believe Binswanger is for “open borders” eventually — so I am not sure how he
will handle jihadists).
Those who paint advocates of open immigration, such as Brook, Biddle and Weiner as leaving borders open with no screening (for jihadists and diseases, etc.) are dishonest.
Dr. Brook explicitly states screening is required in his definition of open immigration in his video. Link is here:

Biddle states in his essay on open immigration and individual rights:
“Open immigration does not mean that anyone may enter the country at any location or in any manner he chooses; it is not unchecked or unmonitored immigration. Nor does it mean that anyone who immigrates to America should be eligible for U.S. citizenship–the proper requirements of which are a separate matter. Open immigration means that anyone is free to enter and reside in America–providing that he enters at a designated checkpoint and passes an objective screening process, the purpose of which is to keep out criminals, enemies of America, and people with certain kinds of contagious diseases.2 Such a policy is not only politically right; it is morally right.”
There are many differing arguments for open immigration — each with their different nuances — many of those arguments for open (and closed) immigration are wrong. So be careful when you lump them all together.
Don’t get caught up in the open to everyone vs. closed to everyone dichotomy on this issue. So people be careful when you paint with your overly large brush when demonizing an imagined enemy.
