The difference there is that the protocol allows inscriptions (as dumb as they may be). Bigger blocks is a different ball game and even if he wants that (which would surprise me) he would know that this has already been played and it has become such a part of Bitcoin’s lore that nodes would reject this again and again

I don’t buy the “protocol allows it so 🤷♂️” line. Email, sms, and voice calls all attempt to deal with spam even though the protocol technically allows for it to occur.
Either way, I’m making a prediction. We’ll see how it goes. I have no insight into Saylor other than what he utters in public
