devs should stick to what they know best; coding. they are inexperienced and naive in areas such as fee markets or finance, much less game theory. most of them have little experience in dealing with ppl much less starting a business. ppl who understand these things and who have knowledge regarding the history of money and economics certainly can help prevent missteps along the way.
That's true for devs in general. Security, crypto, and especially BTC devs by necessity and predilection have deep understandings of game theory.
But yes, they should stick to coding and not (attempt) central management of tx fee markets, regardless of pleas of 'Oh, won't someone think of the users!'
