It's my natural right to own property, with the caveat that such ownership is defined by my ability to defend it by whatever means necessary: socially, physically, logically, legally, etc.

Or at least that's what my country's founders might have believed and tried to establish. We might argue they're still correct in some sense even in spite of a government or society that insists otherwise.

"Every tax, however, is to the person who pays it a badge, not of slavery but of liberty. It denotes that he is a subject to government, indeed, but that, as he has some property, he cannot himself be the property of a master."

To whom is that attributed?

Adam Smith.
