I'm old enough to remember when some people passionately believed that "all property is theft."

Some was, some is.

In the end though, people became comfortable with a certain amount of property of their own.

Maybe it predates me by a bit. Pierre-Joseph Proudhon (1809–1865), argued that private property allows owners to exploit the labor of others without working themselves, essentially stealing the "collective force" of workers.

Parallels.
