I disagree that creating new things should be prioritised[0]. There's too many things already and the most pressing problems have solutions which are not new, just hard to apply for political reasons.
[0] Saying "prioritised" instead of "good", because "creating good new things" is tautologically, uninterestingly "good".
Not everyone can create new things, or create new things all the time. The rest of the time they can make better use of existing things
That too, but my disagreement is more fundamental: even if you can create good new things, there are probably[0] better things to do with your resources than creating them.
[0] This is a small escape hatch for "what if one can only create new things" or "actual cure for cancer".
