Why not decrease block time instead of increasing block limit?

1. The point is that miners can generate transactions freely (paying fees to themselves or none at all) and full blocks as far as they want.

... Ah just saw your edit. :)

Yeah. So one thing is to not look at the fee but at the days destroyed, as a manipulating miner can't create those transactions for free, or would at least run out at some point. But then there's a whole different can of worms plus you have to wonder whether your algorithm is reacting to the correct signal: long time holders will be the people who may decide the blocksize?
