The old people with a reverse mortgage & the taxpayer subsidizing the associated losses.
People who put much of their excess savings into an appreciating home they planned to sell to fund their retirement as they moved elsewhere to somewhere cheaper, but now have a home which as a step function is worth far less.
People who would be quickly underwater if the property market tanks deciding to jingle mail, leading to blighted streets for those who stayed.
Local property taxes pay for schools, fire departments, police, etc.
As far as the state being a perfect provider to step in ... in the US about half of healthcare spending is fraud. That the bill is passed onto someone else is a big slice of that (along with ignoring antitrust laws, local CON laws, illegal to import pharmaceuticals directly as a consumer, etc).
I used to live near Chicago as a kid & recalled this https://en.wikipedia.org/wiki/Cabrini%E2%80%93Green_Homes "At first, the housing was integrated and many residents held jobs. This changed in the years after World War II, when the nearby factories that provided the neighborhood's economic base closed and thousands were laid off. At the same time, the cash-strapped city began withdrawing crucial services like police patrols, transit services, and routine building maintenance. ... On July 17, 1970, Chicago police patrolman Anthony N. Rizzato and Sergeant James Severin were shot and killed by gang members while patrolling community housing for an all-volunteer "Walk and Talk" project. As the officers proceeded across the Cabrini–Green baseball field, the assailants opened fire from an apartment window. The purpose of the shooting was to seal a pact between two rival gangs."
Which land will the free or subsidized housing go on? Will the people spending a grand or two a month in property taxes want the elevated crime levels near their own front door?
