It won’t be long before the users just grow their own, growing decent pot is no more trouble than growing good tomatoes, and once guys start getting into it, they will be ever improving, and selling it cheaply or for cost to their friends, and trading versions of it and so on.

If you have ever been around pot growers or tomato growers, you know how it catches on and develops into a kind of gardening competition among friends and neighbors, roses are like that.

Nonsense. Pot smokers are too lazy to grow their own. /s

This.

If a black-market guy can make a decent profit on his "product" at his price, legal growers should be able to also, despite the heavy taxes (look at tobacco or alcohol).

But eventually, a lot of people will start to grow their own, like your tomato example, and save a LOT of money.
