The concept of "ownership" is a human perception that is imposed upon a noun. Ex. This is an apple vs. This is my apple. The transition from the apple being simply "an apple" to being "my apple" indicates that a subjective change of the human mind has occurred, not an objective change of the apple.
The terms that imply ownership (my, mine, yours, theirs, etc.) are subjective representations. The statement "this is my apple" is an opinion. In order for the above statement to be objectively true, it would have to read as "this is an apple that I use". "To own" = opinion, "to use" = fact.
that means you cannot own yourself or your organs - meaning I can come along with force and take your heart and organs out with surgical equipment and use them for something else, scientific study, to help a loved one of mine with a transplant - even though you'll die I have as much right as you do
false, because ownership is subjective and given by other people to that person - so if a group decides that their friend has ownership of X in their eyes, then in the set of those people it is true that the person owns X and ownership is possible. you cannot mandate against ownership unilaterally
