My concern with the “people wanting to make the ecosystem better to improve the ETH value proposition this driving eth prices up” doesn’t scale particularly well IMO, nor does it foster competition for customers which I think is critical to product development. I’m worried that it will be very easy to reach a local maxima, and there is little incentive for new competitors to enter the market.
As a personal example, I have considered building as Ethereum client but decided against it because there was no profit incentive for me to enter the market.
