This is hyperbolicly dramatic. Nobody will put you in jail of you don't sign a contract. And if you don't pay rent it's a beach of contract and civil matter. It can be very hard to force people to pay rent if they're not paying. All you can do is kick them out, eventually ,there is no jail.

Your dramatic post makes it seem like the cops can kick down your door to get rent. That's simply not true.

It isn't dramatic. If you don't pay rent you're homeless. It's illegal to be homeless. So you go to jail.

But it is true, from a certain perspective.

You're either homeless or you have a domicile somehow. So, many people enter into leases or rental agreements. Then they pay rent to maintain that home.

If you don't pay rent, you don't get arrested, but the constable is actually a law enforcement officer, and the constable is the #1 official who is involved in evictions, so yes, they will "kick down your door" to dislodge you from a place where you haven't paid rent.

And then what do you do, when you're homeless and on the streets? In most urban centers, it's illegal to sleep outdoors or trespass ("urban camping" laws), and so the homeless are often subject to arrest or sanctions because of the nature of their plight.

So the only logical response here is to get housed, pay rent, and keep paying, just to stay on the legal side of things. Ask me how I know.
