You misunderstand. I don't think it's your responsiblity to "process all of your email". You're free to ignore any cold email.

I do think it's your responsibility not to encourage people to spam everybody else, even if getting repeated requests so you can "help people when you're not busy" tickles your ego. If you don't want to help them with whatever it is you do, let them go somewhere else.

You are also making yourself busier, which kind of makes a person question your sanity if you really are busy already. Even ignoring a message is an effort.
