I am aware about this apparently, but the question remains: If you can´t prevent people from using it (e.g. mounting as art on the wall in their home), what is then the value of your ownership? In real art, people pay a lot for an e.g. original Dali, and then there is a whole industry of posters/replicas where you can get the same painting, but for a fraction of the money. With NFTs you pay for the "original" but everyone can use it.
