You answered "Why do you have a component library?" but I think the original question was more along the lines of "Why bother monetizing components that can be copyright-washed in minutes with LLMs instead of having a Donations funnel?"
Aren't Pro components the same as a donation, but then giving you something extra as well.
In any corporate structure it's 10000x easier to get approved to just buy something from a vendor than it is to set up donations for an open-source project/foundation.
PLus you're missing the licensing aspect, part of this is AGPL if you use the free version, lots of places are happy to throw down money to get a commercial license rather than hem and haw over AGPL.
