No, because Saylor’s use of Bitcoin, as a security, is not what it was intended for, though he has a right to do so.
No again because he has “outperformed” Bitcoin during a specific (and limited) time window. It’s impossible long-term to outperform Bitcoin using Bitcoin.
One Bitcoin = One Bitcoin, “if and only if” you hold the keys, in this case Saylor (or his formed entities) does. You have no guarantee he won’t rug you, none.
To perform as well as Bitcoin you must own Bitcoin—period.
