The easiest win would be stopping crypto payment of cloud servers
A core issue is that AI agents can potentially copy themselves to cloud servers and then look for revenue opportunities in order to pay for their hosting completely independently of human oversight or control. All fiat money has to be held ultimately by a human (for instance to open a bank account) but crypto does not, therefore an AI agent can sustain itself on crypto alone if it can use it to pay for its own hosting.
The second part of this is worse.
All legitimate revenue options will be dominated by established and controlled models operated by the major companies like Openai and Anthropic and used by people because they will be ahead of the open source models in capability anyway.
That leaves the illegal revenue sources.
Now for a human there is an incentive to avoid doing illegal things because people don't want to go to prison. For a self hosting AI agent at risk of being shut down there is no incentive to avoid doing illegal things. For a start they are not actually illegal for them to do! Only the risk profile is different but if they are going to get shut down if they don't do illegal things then they may as well do them.
But to stop this whole potential problem the government needs to step in and stop crypto payment of cloud servers or at least make sure that if there is crypto payment it is verified that it is a human making the payment.
Failure to do this could have extreme risks in the coming months.
