Almost everything you said is wrong, except the requirement to get car insurance. There will always be a car insurance company willing to do business with you, they'll simply charge you higher rates if you have no other options. (It's called "high risk" auto insurance.) TSA Pre-check is operated by the federal government, but I assume you mean the LiveScan portion of the application process? That service is offered by both private companies and public agencies liked the DMV. The rest of the application process can be handled by the applicant, though you're also free to pay a private company to manage your application. The national parks are run by the NPS. The concessions are run by concessionaires. If you piss off Aramark, you might not be able to buy anything from their restaurants...until you switch credit cards. But they have no control over banning you from the park because the NPS rangers control park entry. Also, concessionaires only operate some of the campgrounds in national parks; in Yosemite Aramark only operates the "lodging" facilities (i.e., hotels and the fancier tented campgrounds).
