First, you have not made an argument that a pool hopper is dishonest; you have simply claimed it as if it were obvious. I asked for an argument and you give me nothing.
It is obvious, gaming the system for an unfair share is dishonest. The scenario I described is evident of an example of how you are gaining money while others are losing it. See my first statement, you simply passed over it and refused to even give it due consideration because you have your rationalization in your head. It's like trying to convince a Christian that the idea that the earth is 6,000 years old is ridiculous, you have your vision of the world, and without realizing it you dismiss the evidence to the contrary.
Proportional payouts are perfectly fair, if miners were honest. The fact that they aren't means that the pools have to find alternatives. The PPS scheme is problematic, since it pays regardless of a block being found, and the pool operator can lose money. I'm sure there are other payout schemes, and hopefully they will be implemented, but that takes time and shouldn't even be necessary if it weren't for the pigs at the trough.
Again, I did, remember, I mine at btcguild where they go out of their way to discourage people like you. Problem is, there are still people who try to game the system, and I find that despicable
