you are forgetting something. Unless the right to travel freely is protected by something other than the state you cede your right not to travel to people who are born to parents in that state are not being given the free choice not to cede their sovereignty. Therefore, either people do not have the right to cede their sovereignty as a group because their is no way to do it without impacting others rights, you haven't actually thought this through completely, or you don't really believe in individual rights.
The reason the federal government exists is to protect against large groups from taking away the rights of individuals even if it is done by mutual consent, until you understand that you don't actually understand the federal system. Which, again, makes my point, the federal courts were doing their job.
I'm not forgetting that. And yes, you need the federal government for certain things. Interestingly enough, the AoC included a right to travel. I have said (not here because it has never come up) that there should be an amendment that includes the right to travel written for quite some time.
You do not understand federalism as defined by the authors/ratifiers of the Constitution. Even the federalists (who were, in reality, nationalists) did not agree with your sentiments. If you want to understand it then you must read what
they wrote. Every time I mention what they wrote you scoff and declare that I can't possibly know what they meant. You do that without reading what
they wrote which is funny.
Again, you are free to hold your own opinion but you do so wilfully ignoring what the original authors wrote. That is your perrogative but do not tell me that I don't get it when you insist on NOT reading what is available to you.
The first line in my signature applies here.
