You mean just shut down all entry into the US? That will send the world economy into a tailspin, but so be it.
Essentially, yes - shut down entry for non-citizens and non-residents completely. The left has decided that judicious use of the power to prevent entry is unconstitutional, so let them deal with the consequences of having to apply injudicious use of that power.
The key, though, is to continually educate the public (without going through MSM) about the cause of the need for injudicious application of that power - the fact that feral federal judges believe they have the authority to rule over the president in this arena, where clearly they do not.
