I understand your point that applying changes is consensus based and it's the best way ever invented. And it implies that Saylor can have his own opinion, just like you and I do. Clearly he can have somewhat bigger reputation effect on the consensus mechanism than we do, and he earned it. Yet I don't think he's in power to stop enthusiasts, but he has same rights as we do to spread his vision.

We can debate on how many active contributors does BTC need for the time WHEN absolutely necessary changes to the protocol will have to be made. But a situation when BTC needs a new quantum resistant hashing algo and there's noone in the world able to do it - is impossible to imagine, imho.

I don't see current situation as anything problematic. There are enthusiasts who work, and they sometimes become too enthusiastic lol, but there are those who make their work more difficult and it's just fine. I like this balance of powers and it works great, imo.
