In the case of software, the resource is time (you could build/host/operate that software yourself, but it takes a heck of lot more time than you're willing to spend so you trade money for the product instead), and you can't reduce the scarcity of time.
For instance eyebright, while common, resists cultivation as it's a hemiparasite and requires a host plant to grow.
Sometimes a good instructor makes all the difference in the world.
And in no way do I want to take away from her insight and skill in popularizing and communicating these concepts. Clearly she is good at what she does.
One grower of Venus flytraps set aside 100's of tissue-grown clones to evaluate each theory proposed, and determined that their roots were highly susceptible to fungal attack. Presumably, they had lost this (perhaps metabolically costly) genetic defense, because they were growing in substrates that were naturally hostile to fungal growth.
Anyway, the slightly more fascinating part to me was that, for this pro grower, growing hundreds of plants on a lark was a fairly trivial exercise. I cast aside my prior image of bunny-suited lab techs with pipettes and agar jars; this was full-scale production line.
The irony is that VFTs aren't even considered endangered, per CITES definitions. They only grow in a few counties in the US, however, so their survival is nonethless precarious and worthy of heavy-handed defense.
