but then again there's nothing really natural about how I grow cannabis.

Yeah, the lamps are very artificial 😅. Since it's legal, I see no reason to grow indoors, other than the one you mentioned.
In fact, I think growing under lamps is kind of... silly. In an earlier post I discussed all this...

I got a 1500m² garden in the middle of nowhere (no electricity, no water) and in an ideal world, I'd just grow some 100 plants and select for the best and breed....
Little work, no cost, no pollution, no overhead, no worries.

I got this 2 m² south-facing balcony here, some stories up, in an apartment complex.
If some five fingered creature managed to get up here to touch the plants, I'd be very impressed.

While I feel what you are saying, I am opposed to the mindset that 'the humans are the problem' - It's so cynical, it hurts my soul. Maybe I'll write about this someday, but my hand hurts and that's a long story...
