Reminds me a little of the hoohaa when they introduced unleaded fuel and phased out leaded (although I read recently that leaded fuel was still being produced until a month or so ago).
We all adapted and overcame the obstacles, either by using additives, or forking out for major head work (or some just bought a new car that was suitable for unleaded).
Similar will probably happen with current classics - I've already replaced fuel lines for ethanol proof. If the tank suffers, will replace with a stainless, and if the carb gets effected, will fit a throttle body kit. If we lose petrol completely, I'll get an electric motor banged in.
I'm sure the puritans will grumble, but I'd much rather be out driving, than polishing a redundant ornament in a shed.
