Since that didn't actually happen, and I'm also buying my carrots at the supermarket, we can probably deduce that it's not home-grown supply that's the problem here.
... but your underlying point is correct. A better analogy is probably basil, which a large percentage of buyers actually just keep their own plant at home.
Brewing beer is pretty dang easy.
I know you mean hybrid strains bread for high potency. Prohibitting those if otherwise legal would require a legal basis.
I thought one objective of legalization was to avoid laced product. Of course lacing weed to make it appear more potent and to be addictive is still forbidden. I have no source for that. Chalk it up as purported rumor. I've heard police test a crusher (weed grinder, whatchamacallit) positive for co-alkaloids and amphetamin in Germany.

If you want to drink wine from hybrid grapes in the EU, you have to buy import (Moldova, North Macedonia etc) or homemade (usualy low quality) wine.
Hungary, Romania and Bulgaria had to uproot most of their hybrids upon joining the EU. The same would happen to Macedonia.
The article only says that hybrids from the 19th century were inferior; suppose taste wise. Which is a matter of taste, but likely reflected in sales. The upside is resistance to fungi and such.
