I agree that I don't know how much is enough, and that nobody really can know how much is enough. But that doesn't mean it's impossible to overspend on security. Bitcoin's model for how much to spend is basically just "pick a number". Right now it's 37.5 BTC per hour. In 2024 it will be halved. Is it way too much now? (I suspect so, but I don't know so). Will it be too little after the halving? (Probably not). The next halving, or the one after that? Who knows.
