I'm grateful that you would take the time to speak with me. I know it's an expensive thing to do.
I'll start with ~~a humorous point for an autistic person~~ the worst kind of pedantry. An object cannot be no one's and mine at the same time. If I own it, then it isn't no one's. To the degree the CPU is indeed yours, then it is someone's CPU. Obviously, there's some conversational implicature embedded in your claim here, and that's what we're here to clarify.
For the record, I'm on your side. Your overall argument is something everyone needs to hear. So, I'm not here to destroy your assertion, but I think it should be weakened. There's a lot packed in there.
I take your proposition to mean, roughly, that the CPU in your possession is something only you have a cluster of moral claim rights to (which corresponds to a cluster of moral obligations of others to you regarding that CPU), with no possibility of overriding reasons, caveats, or provisos. Now, you could be speaking about political claim rights, but I don't think that's the case here (correct me if I'm wrong). Is that a fair interpretation, and do you wish to maintain that? Can you think of any exceptions? Are there any adjacent possible worlds in which that is not the case?
I suggest you are incorrect to assert that "no one is entitled to my CPU time." I agree, however, that advertisers do not have that moral claim right.
