Not so. I'm not advocating the elimination of the federal government, nor am I advocating for a reduction in the role of the courts. The 14th amendment exists, incorporates the inalienable rights in the constitution against the states, and I believe that is just and true.
That said, yes, there are logical, rational disputes on what rights allow one to do or not do, and yes, those rights are treated differently within arbitrary geographical boundaries. This is true today. There are people in jail right now for marijuana possession because they got caught with it in the wrong state, but that pales in comparison to the number of people who were jailed for marijuana because its illegality was imposed upon them by federal decree. Similarly so with immigration, gun rights, and a variety of other topics.
The law isn't settled on every subject, and there are often reasonable interpretations by well-meaning people in either direction. Having the federal government set policy clearly doesn't solve for every edge case, and I maintain that if you are caught up in a "bad place" by an interpretation of rights that disfavors you, it's a lot easier to relocate from say, California to Arizona (or vice versa) than to have to abandon America because it disfavors your rights.
If, for example, states were allowed to implement current TSA procedures as they preferred, you would likely have states competing on rubrics of security, while others competed on efficiency, or perhaps traveler friendliness. Now, instead of alienating travelers from abroad from visiting America, perhaps they are only alienated from flying into certain states.
As for the corruption angle, again, I'm not proposing we abolish the federal government, merely reduce its workload so that it can function better as a watchdog over the states to prevent and squash corruption. Having better representation locally and federally is of course a good thing, and especially so as it better empowers the adversarial system to hone in on those things that we all do agree upon, and protect those rights from being infringed upon.
Lastly, I'm not suggesting that it's a silver bullet, and that any of my ideas "solve" America, but I do think they improve upon the checks and balances that we're used to having, and allow for more freedom within American borders than we currently have, and more insulation from the legal interpretations of presidents as they are elected, and I think that's a net good.
