I believe the person you were replying to was referring to land when he said property (which is a normal term to use, if someone asked me "are you interested in looking at a property?" it would pretty unambiguously mean land / physical building).
Not that it means his stance was correct, but your argument isn't addressing his point.
Property is more than just land. People have titles cars, boats, copyright over books they've written, stocks, bonds, savings accounts, furniture, clothing, timeshares, patents on things they've invented, etc.
At any rate, in all three of my examples, money changed hands for work creating property. That money could be used to buy property, physical or otherwise.
I don't think you understood my point. The word "property" just has two separate definitions in common English, one is the one you are using and the other is verbatim "land" (which happens to be a subset of the first definition).
At least in my dialect of English "a property" would always always refer to land (e.g. "steal a property" is nonsense).
