Theta depends on the implied volatility…but short a share doesn’t involve theta. Only options have theta and there is no % cost to be short an option, just margin required. Generally a high cost to borrow is an impediment for anyone to short.

If an MM goes insolvent the bank that clears them has to cover it. Eg archegos in March. But for example, BoA clears Susquehanna and citadel. Worst case scenario, those two MMs could probably take down BoA or at least get close. The security levels would be clearer (bank), exchanges/government. Not a concern IMO.
