That’s kind of a “purist” approach. With legalization, the market expands to the point where boutique breeders make up only a small part of it. The majority of the market needs to be filled by bigger producers, who can only serve it through mass production. And some companies manage to do that really successfully without compromising quality too much. That’s what happened in Europe. It’ll come to Brazil too 
The reason seed production moved to Spain is because of their partial legalization. They can pretty much produce seeds legally, but they can’t produce buds in large quantities. And here’s the catch: I think good breeding practice means producing enough buds to actually see the results of the breeding, not just seeds. And they’re somehow legally limited in that. Full legalization would give them more freedom and peace of mind, which is valuable for long-term breeding. But I’m not based in Spain, so if someone could check my intuition, that would help.
