Who the fuck is going to pay for miners if not people exchanging Bitcoin for other things? If all Bitcoin is locked in multisig bridges, these federations will realise they can settle between each other through an even larger multisig or LN channels and never pay fees on chain.
You expect the current hashrate to persist despite no fees forever
If the hashrate falls, what does Bitcoin offer that Litecoin doesn't? Nothing is the answer.
Everything can ossify, that is not a selling point, not until you have a Script that can emulate anything we might need in the future... FFS that is why Satoshi invented Script instead of hard coding all "approved" spending conditions... The fact that Script got neutered since is an accident and a failure that Bitcoiners started to worship for some retarded reason.
