It would take too long for the agent to earn enough money to have a single transaction that could be used to top-up the account; you can't do many micropayments to top-up which is the issue. And on top of that, the whole point of agents is that they can perform menial, small tasks for you to focus on the big stuff, and no one will want to pay an agent $5 for something small, especially if it's not their own agent. Eventually it will also primarily be agents communicating with agents, and that definitely can't be done with account-based funds at scale with humans expecting the agents to run along on their own doing their thing. It's not that agents need Bitcoin, it's that they need micropayments, it just so happens that Bitcoin makes micropayments easier.

ok, decent argument I'm not convinced though. I imagine if any of the problems you're bringing up are real visa or paypal or whoever could easily spin up new features tailored for ai agents. what's stopping them? imo bitcoin's value as a transaction mediun comes from censorship resistance, regulatory arbitrage, and privacy. agents don't really need any of these
