Sorry, just used to the Bitcoin community, who tend to act like the blockchain they have speculated on is the only one that has ever existed. What are your reasons for bitcoin maximalism?
Bitcoin's liquidity and network effects, in a nutshell. I don't think a competitor will be able to match Bitcoin on those fronts. And it's not just about the developer and technology community, it's about the media, governments, companies, investors, regulators, financial institutions and even regular people who are getting used to the name Bitcoin.
But, honestly, it doesn't matter. This stack is blockchain-independent. Whatever blockchain or currency ends up succeeding in the long run doesn't take away from the fundamentals of this stack: decentralization of data and processes, cost reduction, and consumer power.
I focus on the Bitcoin blockchain because that's what the market has chosen to build on top of because there are no better alternatives yet. We'll see what happens if and when they come (e.g. ethereum), but I worry that it'll be too late by then and the market won't take it.
