That's a good point. When I get into hating on ads, it's easy to forget about people for whom "micropayments" would not be so "micro". So the system would need a free option. Maybe just with ads. But how could ads be worth anything if only poor people viewed them? Maybe something like a distributed library system. Non-poor freeloaders might be problematic, however. Maybe add a delay for free access. Or reduce bandwidth to slow loading.
