The Guardian reports that "socialism" was the most looked-up word on Merriam-Webster's site this year, a change the American dictionary publisher attributes to US presidential candidate Bernie Sanders, who has positioned of himself as a "democratic socialist".
As a socialist (or communist) myself, I personally think it's great that especially people from the United States try to figure out the meaning of the word beyond McCarthyism. I'm glad that people show interest in politics and finding out about positions of candidates.

All you're doing is using an overly-strict interpretation of the concept of ownership, nothing more.
Yes, governments get to demand taxes. And yes, they may have the power of compulsory purchase. Provided these aren't abused, there's no issue, and it's rather meaningless to say that land ownership doesn't exist in the USA because of these things.
The question is a practical one, and in practice, land-ownership is generally well protected in the USA.
