So without a property and/or a vehicle you're basically treated as less than by the state.
Homelessness is being criminalized more and more in the US and that'll give a licence for it to spread globally.
The solution is cheap back-alley welded cycle rickshaws. If enough homeless people could get a simple cycle platform with a lockbox and room for a mat or tent it could change things.
They are no longer homeless, they are in their vehicle on the public highway or whatever, officer.
The small increase in security, with the lockbox, could result in more dignity imo.
Large traffic blocking protest actions become an option for the homeless, similar to the car protest actions seen during lockdown.
The state may come to regard this action as so visible and inconvenient that they may be forced to do more than pay lip service to the issues.
Sure there would be a reaction, but consider the concept. 200 rickshaws suddenly in an urban area. Just the attention drawn would be something.
You're talking about smashing someone's vehicle and possessions. Ofc it happens but there would be recourse.
