That's as maybe but you'd still need sufficient money to work backwards and arrive at that conclusion. I enjoy producing Techno but I can't just quit my full time job in order to do that (Much as I'd like to!).

Are you saying there aren't any people that can't make a living from producing Techno?
Not at all, a couple of thousand probably do. It's just not feasible for me. I can have that as my "ideal", which is maybe what he's saying in the video but I don't see it as being feasible.
You not seeing it as feasible makes that true for you, not meant as a dig, but small setbacks will confirm you are “right” sabotaging your potential.
Speaking from experience working my 9-5 grind for 30 years with a music “hobby” 😀
I think Gigi is trying to tell you that the thing you think is impossible, is actually possible if apply yourself to your interest.
It isn't that you can't, just that you won't, until you decide that you can.
