Sure - I think there's a possible long game here where we're able to technologically engineer our way back to producer status.

Bio-engineering is one route (KloraDerm), but I could see alternative routes that are essentially just chemical/material sciences.

I think it's probably an incredibly complicated supply chain we'd have to really work through to make sure you can synthesize all the required components without going through something living, but we know that producers exist - so there's hope.
