> Why can't the government stay out of my business?

As I see it, the moment you leave your private property you are interacting with society and it's not your business anymore. Of course you need the option for a bigger van, but that doesn't mean that nothing can be done about the SUVs. You can't just drive around on public(!) roads and think you're not bound to the rules of society. Also, it's a private citizen proposing this and not "the government". Environmental legislation is a product of changing attitudes in society and not some deep-state, technocratic action.
