I'm surprised this mindset is still a thing.
High end crafters don't care because, as you said, we have more gil than we'd ever use. Even if you nerf crafting to the ground, we'll make far more gil because we have patience and can learn the markets. We don't need gil, it's a side-distraction, we just want something at the high end to keep us occupied.
The thing casual crafters don't realize is there is only one pie. By that I mean there are a limited number of buyers in any market. What do you think happens when a single pie is offered to everyone? It has to be divided among 10000 and all you get is a crumb. You'll never get that slice you grudged us for, because the slice took a lot of work and patience and it's impossible to divide among an entire player-base. Now you've destroyed that pie in your greed to have it (Facet gear is completely worthless and sells for peanuts) and will never make the sort of gil we have because nothing you make is worth anything. Enjoy.
