I thought that was the vision behind PRESTO (implementation, of course, being a whole other story).

VIA's a bit tricky in that you buy tickets in advance. But there's no reason such a thing shouldn't exist otherwise.

Right. But we don't have PRESTO -- are we the only ones to reject it?

You could still allow on-the-spot VIA purchases using PRESTO (or similar system), the pre-purchased paper tickets would work in parallel. It's the same in Japan, you can purchase paper tickets or use your SUICA/PASMO.
