I do get the sentimental value though... If ever I live abroad, I would like to surround myself with ornaments from my country and heritage. Not only for the nostalgia, but also for my future kids to know where they are descended from. I do know that kids and us as parents will have to assimilate to the new surroundings, but I don't want to forget where I came from.
Those paintings are really good by the way and that NFT idea seems marketable.
