I will say that the generosity approach is the most effective. I've gotten so much more by giving stuff away. I still have not paid for a cut.
It's also worth pointing out that phenos found in seed runs from your vault can yield plants that beat any "clone only" in quality. The probability of a typical "clone only" BOTH being selected from a large seed population and being maintained and dispersed around the country is low. The probability of you finding a great pheno in a pack of seeds is higher, I would hypothesize.
I would not disagree with any of that, but would add it assumes that grower has time, focus, and space to pheno hunt, which not all of us do. I wish I could pop ten packs of the same strain and select ten from that group to grow out and keep the best from those, after cure, but that is well-beyond feasible for me in the foreseeable future. I pop one pack at a time, maximum, and try to use my own discernment to choose a decent mom early on. Then there’s the hype factor, I feel like cash croppers want lots of yield, and preferably even more hype, on the strains they offer. Cuts get the hype, in the commercial market, inevitably.
I was given some desirable cuts (Durban Poison and Bruce Banner 3) a few years back by an old neighbor. It was because of our mutual generosity with each other as neighbors, before we identified each other as growers, that he was happy to share. I am currently rooting some clones of OBS and CnC to give him, as he recently lost all of his mothers. Sharing is a cool guy winner thing to do.
