back up a step.  miners get paid to insert those CP records into satoshi tx's in the first place which incentivizes mining growth and thus more security and thus less chance for subsequent attack on those same satoshi tx's.  now move all these CP tx fees off to a SC that can't be MM'd.  this deprecates the MC.  and there will be thousands of these insecure SC's as i think only a few SC's will be MM'd due to mining capacity constraints.
