Incorrect once again. You’re describing inertia not monopoly. Core’s dominance comes from historical trust and validation not lockin or barriers. The disincentive you mention is risk-aversion not enforced control because any client replicating consensus behavior can replace Core if the network prefers it. That’s not structural monopoly that is voluntary coordination or nakamoto consensus.

Your only counterargument is to make a distinction without a difference.
> any client replicating consensus behavior
That's the rub. No client can guarantee a byte-for-byte replication of bitcoin core behavior. That's the reason core is dominant. That's why we need a consensus library. So all clients can run the exact same code and guarantee the exact same behavior when validating blocks without being forced to run the same p2p code, mempool, policy rules, IBD, template construction, wallet, gui, etc.
Why are you hyper focused on enforcement? Nobody's talking about enforcement but you. Is this like a fetish or something? You're focusing on the wrong thing, bro. It's an utterly irrelevant distinction. It's a straw man.
Anyway, it's been fun. Last reply. Deuces. ✌️
I've already said I agree we need a consensus library and that we need multiple clients, my only argument is that Core is not a monopoly.
