Earlier quoted context omitted.
Isn't this like saying "not your house, not your possessions" ? But landlords cannot just take or misplace my stuff, especially if I pay rent and have some rights.
"But landlords cannot just take or misplace my stuff, especially if I pay rent and have some rights." They sure can. Years ago I had a shitty landlord clear an apartment I'd moved 95% of my belongings from but before the term of my lease had ended. Now you may have some legal recourse, but the cost/time associated with litigating a matter like that tends to outweigh the remedy.
The existence of legal standing is what defines the property rights. If you're going to move the goalposts to "you don't own it unless you have legal standing and the means to pursue legal recourse", then you might as well say that only the extremely wealthy have any property rights at all.
