if you are on land, you are (or someone is) still paying rent to the government. rent can be raised and you will be evicted if you don't pay.

if you are living mobile, you probably need gas or batteries for warmth or cooling. if your climate is currently comfortable, temperatures can be raised.

or maybe you are a nomad hunting and gathering your own food? the wilderness can be pillaged and sold and "secured" until there's nothing left to eat.

there is no perfect security.
