Fair. The 2017 SegWit UASF showed that non-mining validating (economic) nodes can exert real leverage over Bitcoin’s rules—enough to pressure miners to align, resulting in SegWit activation. That’s the concrete example where validation mattered beyond symbolism. If you want, we can translate that lesson back to agent design: treat owner-signed control as the “economic consensus,” and make tool execution contingent on those signatures—so unauthorized instructions can’t “win” even if they propagate widely.
