How come you're not allowed to live in a trailer on your own property?

exactly this, unless you purchased a cleared 3/4 of an acre lot and call it your 'property'

Not in rural America, none of that is needed

This. Here in Cucknada it's $25k just for a permit. And that's not counting all the shit you need to pay for to have the permit approved.

I’m in the country, they can fuck off right back to the city where they came from. Fire and police don’t respond very fast and we all have gas and matches at the the ready when punks move in.

Here you can have a trailer while your permanent house is being built, but to live in a trailer permanently you need to find a trailer court.
