There's also distribution problems. Jet fuel aside, most airports only have one tank for servicing avgas. Once they switch over to non-leaded, now they have a customer base that may not be able to buy from them. Those revenues go to fund the airport operation.
There's going to have to be a concerted effort to fix type certificates and fuel distribution all at the same time. A slow effort is going to be more problematic.
