fair point, for creative stuff whether or not its worth is really billions is another discussion which might touch ethics but is not always an obv violation.

It can really be a grey zone though since some inventions could really improve humanity as a whole (such as those in medicine) but when capitalised becomes accessible only by a certain class and makes the inventor possibly a billionaire. Now if you categorize earning billions from this as non-ethical but earning billions from other creative processes as ethical this will likely create a loophole. So I am still in favor of putting these in the same bag.
