they would still lose out over the long run as they would receive a lower amount of payouts.
If your mining operation is a block eruptor.... you have nothing to lose.
A "lower amount of payouts" from nearly zero, is hardly distinguishable from nearly zero. Many of the pools have a mechanism such as pay per share, so the withholder doesn't lose any payouts even if the pool is strangely 'unlucky'.
They're paid just by "proving" they are working on the solution.
Without an extra kickback for providing the solution when they find it, however... the pool operator, and the majority of the miners need the solution to be found early a LOT more than the individual miner does.
If you had a block eurpter then you would be loosing out anyway as your electric costs would exceed your revenue.
We can ignore the fact that the chances of a block eurper finding a block are slim to none.
You also have the ethical issue that when you are mining on a pool you are essentially promising that you will provide the pool with work that your miner does and in return the pool gives you payment based on your shares. If the work your miner does involves finding a block then that work is due the pool.
