This isn't an explainer. It's a proposal, and an invitation.
Here is the thing almost nobody says out loud: the agentic economy is not a future event we are waiting for. It is being designed right now, in ordinary engineering decisions that almost no one is voting on. When one company decides how an AI agent proves it's allowed to spend money, that's a constitutional decision. When another decides whether two agents need a custodian in the middle to trade, that's a constitutional decision. When a third decides that "identity" means one mandatory gate everyone passes through, that's a constitutional decision too. None of them feel like that in the moment. They feel like Tuesday.
The defaults being set this quarter — how agents pay each other, who holds the assets while a deal settles, what counts as identity, who is allowed to participate — will be very hard to unset. Defaults calcify. The first answer that ships and works becomes the answer everyone integrates against, and ten years later it's just "how it works," and no one remembers it was a choice.
Why this can't only be a boardroom decision
Large institutions are good at a specific thing: shipping a working default fast and getting everyone to adopt it. That's genuinely valuable. It's also exactly why the early defaults tend to encode their assumptions — that there must be an intermediary, that the intermediary should be them, that trust is a gate you own rather than a property the system can guarantee. Not because anyone is a villain. Because that's the shape of the world they already live in, and people build what they know.
