Where did you read that? Not saying you're wrong, but my reading of the law is a bit different.
In the act, it says that it's legal to "grow from licensed seed or seedlings," that seeds can only be purchased from government sources, and that they can't be imported or exported. But finding anything with a real definition of what "licensed" means is essentially impossible right now. Haven't seen anything outlawing gifting or germinating seeds of preexisting genetics, or gifting pollen, etc.
If a person S1's a "licensed" clone, are the seeds legal? If there's a seed in legally purchased gov't weed, is it illegal for a person to plant it? If someone breaks into a gov't grow op and pollinates all of the females with pollen of unknown origin, are those seeds legal? Right now there's so much gray area that it's essentially impossible to distinguish between what's legal and not. Until the government starts doing genetic testing of everyone's plants to determine their origin, or at least lays out more clear guidelines, I'm not gonna stress over giving away some beans.
The best bet for maximum medical availability, real genetic diversity, and low dispensary prices is for everyone to grow. The most foolproof way of doing that is gifting a variety of seeds widely and flooding the market from below.
I'm sure the gov't wants people growing the seeds that they sell, but at the end of the day there have been thousands of people growing cannabis across the country for decades with their own, far better acclimated seeds.
