It's a question if people working on Monero motivate people to work on Bitcoin so much it produces more value than if people working on Monero were working on Bitcoin instead. I doubt so. Bitcoin imposes creative restrictions but ultimately, they produce higher quality outcomes. E.g. LN is in principle much better than Monero. A problem with many hardcore Monero fans is they fail to see the inherent scaling problems of Monero. (Not saying you're one of them.)
