I don't think I missed any of your points. But you also didn't answer my question.

Did you know that a drivechain does not require a new unit of account? They could function using Bitcoin as a unit of account. One of the properties of money.

It's just a coincidence that some drivechains could choose to use their own shitcoin.

I predict the only drivechains that would last more than 2 cycles, would be the ones to use Bitcoin as their unit of account.

Edit: Here, friend, have a smile from a fun youtube video about coincidences.
