Usually that only makes sense if other people's use of it makes it harder for you not to. For example, you can want a 4-day working week but still work 5 days because you'll lose your job to a 5-dayer if you don't. But if it was forced on everyone, you'd be happy.
Violating other people's copyrights while still exploiting your own probably means you just want to pirate stuff for your own selfish reasons. If you were against copyright protections in general, you wouldn't be choosing MIT or GPL for your open source code.
