Actually the Trump administration is trying to strip legal status from people and deport them by way of an obscure law that gives the Secretary of State the discretion to do so if they deem those people a threat to the foreign policy goals of the US.

If these laws are still on the books when the next D administration takes over, they should use them against Elon, Thiel, etc - strip them of US citizenship, deport them, and nationalize their companies (followed with repealing those laws)
