This 121 very discussion is ludicrous.

This comes down to a “make vs but” decision”. Is it cheaper to acquire one with “potential liabilities” or start from scratch?

I know many people think that there is value in getting an existing cert plus crews.

Guess what? It is likely to be a lot better to start fresh. Neeleman will have zero problems getting a 121 cert. and people will line up around the block to fly for Mozy.
