Are you impying Monero was pre-mined? Or just speaking generally about crypto?
Monero is FOSS. Anyone is free to leave, join, or make their own network fork. All users currently on the latest fork are voluntarily using it because they value the upgrades, devs, and community of users. If not, they would sell and dip out. No one could stop them from doing that. Aren't you guys about free markets?
Imagine the real world worked like that. Everyone was forced to be compatible with old tech like CDs and could never progress. If you and a few others want to use CDs that is fine, but no one is obligated to be compatible with you for eternity at their own expense.
