You were arguing that having control over something (as in “being able to maintain/repair, modify or even resell” it) isn’t a requirement for the thing’s ownership?
Then what does “ownership” entail? Being allowed to use the thing but not modify or repair it? I’d argue that this isn’t what “ownership” means.
Then what are? Why wouldn’t the ability to maintain/repair, modify or resell be requirements for ownership?
If “ownership” doesn’t have a unified meaning, then I can interpret “ownership” as the ability to maintain/repair, modify or resell the bought item.
