Obviously, yes, people are - and should be - constrained in what they can do with their property. Even the most capitalist systems on earth place restrictions on property. I didn't think it was necessary to caveat that control of private property is not absolute or without consequences. I'm not aware of any capitalist systems that do not put greater protections on people that control large amounts of property (see monopoly, environmental, antitrust, public securities law, etc. Most of those are basically irrelevant to people who don't own large amounts of property).
The point is that for property to mean anything at all, an owner must be allowed to direct the use of that property. What's the point of owning a house if I can't make any decisions about what to do with it. I don't really own a house if I can't decide that I want to live in it, or to sell it.
