And pay a difficulty penalty and lose full blocks because of it? Even if
fees are somehow high enough to compensate for the lost reward, it still
requires miners to collectively decide to raise the block size for it to
make sense individually. An individual vote will not raise the limit, but
it will cost the miner money.
