I recommend reading the federalist papers they going your own way on everything is something that is treated with distain. Precisely because number of barriers that would develop between 13 or in our case 50 different states is innumerable imagine you had to have 50 TSAs, and 50 different FAAs, FCCs, FDAs, USDAs instead of 1 each. The solution you seek to poor regulation is not no regulation but Better Regulation (which includes burning some of the bad ones but also includes having replacements)
I think the unpopular but true opinion is that the government is surprising efficient and good at a lot of things. They are not 100% efficient but neither are companies and the private sector at large. There is certainly negations and discussions on where funding should come from but a large part of government success in the USA is that the federal government assumes state debts and gives us the worlds best credit line. This is something that happened 20-30 years after the nation was formed. We abandoned the article's of confederation because they were such a cluster fuck and a horrible way to administer things. The Federalist paper enumerate several huge problems with the state's go it alone approach naming states on the interior basically wouldn't have to fund any military since they could never actually be attacked and it would be unfair to those that would have to, too the point they likely would just not do it and in a time of peril we'd be screwed. But the are several other reasons to not reinvent everything 13 or 50 times.
Also your analogies need work. The idea that the government under previous admin were beating you up at the bus stop with onerous regulation is ironic considering the current admin is literally beating and deporting people at bus stops. I'd argue there is no regulation like the end of a boot.
But also the remedy is childish too, uber is built atop a federal system that established wildly unprofitable networks because they benefit society in non monetary ways. And now that those widely profitable networks exist you can uber instead of taking the bus. But Uber would not exist today if the internet infrastructure took 2-3 longer to get standard convergence because there was no federal body to say we are building the network this way because we are paying for it.
I hope I am no to dismissive either but rather I am highlighting that the idea the states don't do anything isn't really accurate. Because states host all of those federal run agencies. There people manage them the river service isn't run in Hawaii or anyone state but distributed to states who have linked interest in rivers local to them. Its organized by the federal government but run precisely by the people who care and live in those regions.
