The most famous rant on this is Marx & Engel's manifesto. Chapter one explains how history works, making similar comparisons from their day to older days. The second chapter describes communism's aims. It's also (largely) a rant about the bourgeois.
Anyway, like most Marx, it's hard to translate to concrete terms. One unambiguous line stands out though. "..the theory of the Communists may be summed up in the single sentence: Abolition of private property." - Communist Manifesto
In the very next paragraph, ambiguity re-enters. Even in theory, it's very hard to flesh this out. ...It's especially hard in the context he's most interested in: urban industry/society. Replacing all property with a "commons" is easier to imagine in a rural/village context. Rural commons exist.
I think Marx got the idea from a rural context. Formal and informal privatisations of agricultural commons were part of his stated inspiration, iirc.
Anyway, I think the basics are trivial. Property is effectively income generating by definition. If aristocracy is immoral, then property owning is immoral.
To me, this is a reductio ad absurdum for fundamentalist thinking... kind of like the monty python witch trial.
