Except block your IP address, or your user agent, or the pattern your software makes when it connects.
Yes, that will cause potential issues for other people, which is why they tend not to do that, but if you trivially create a thousand more agents, and potentially trigger a degradation of service, how are you different to the people who block junctions at traffic lights?
I'm not keen on inconveniencing people, and "it's not that bad" is a poor argument for doing something that someone has explicitly asked you not to do.
I think you agree with me. If someone is abusing your website, or even just doing something you've asked them not to do, you can't literally kick them out like you could in person. There's all sorts of techniques for blocking whatever they're doing, but if they're determined and your website is still accessible, they can come back.
That's why it might be reasonable for laws around this sort of thing to be different in the virtual world.
