Coming from the digital art space this is wrong, but comes to the correct conclusion. It won't be a problem if Bitcoin is ever used as currency because it will price out 99% of creators and collectors. The scarcity part is way off, there's plenty of scarcity in the digital space and plenty of collectors including from the trad art world and institutions. I've heard lightening was having problems, they'll have to figure it out, but main chain will price it out.
