And that's precisely why we need to keep all those TX's on the mainchain.
That can't be overstated, Bitcoin won't / can't securely scale if those fees move somewhere else.
Federated Sidechains are ok as people trust the server owner enough to do business with them, there is a balance risk reward.
But changing the Bitcoin rules to make tools to move those fees of the blockchain and calling it an upgrade to the Bitcoin protocol is short sited or just plain evil.
