A tenant who falls behind on rent isn’t a squatter they are still a tenant and normal procedures already allow for removing the tenant in a reasonable time frame. The issue that obtains some places is that courts are too poorly funded and over burdened to deal with issues in a timely fashion.
A squatter is someone who moves in without paying. This gets ugly when as above court issus applies and squatter situations get in line with normal eviction.
WA instituted an expedited process that allows for removal of folks who were never tenants with just police so this doesn’t happen.
That is a smart solution to actual squatting fully funding whomever handles your eviction cases is another.
If you want to take it to the next level look at Finland who almost eliminated homelessness by housing people who are temporarily in a bad way and Europeans generally providing support for those with health problems.
People who fall behind usually aren’t stealing from the landlord and celebrating they are usually falling into a financial hole and living every day in increasing stress as they scramble for a solution. Ask me how I know.
