People like YoungRippa and Razor are obviously at a huge advantage here. Brandon Sanderson didn't launch the largest Kickstarter ever because he listened to Malin to get his youtube channel to 10K subscribers either. When Rippa said he put $200K down on this up front my Eastern European potato brain couldn't comprehend it.
But we live in the age of the Internet: /ic/ has a terrabyte of free(read.: stolen) learning material on drawing alone, I can google for any art related question I'd ever have, I can have Amazon ship any art supply I need and I can upload my work anywhere I want with a push of a button. It's never been simpler to learn, create and push something out there.
You can rightfully argue, and I'll agree with you, that to plebs like us the real challenge is getting eyes on our work and to earn a living from that, because we can't start asking for $25 and $35 for a book out of the gate. It's a long process and getting big obviously takes a shitton of effort and some luck, but today people can do the work alone without trying to beg their way into a few gated institutions with the power to publish something, and that's where the "you can do it too" mentality comes from. Obviously I'd never be able to raise $200K or a mil out of nowhere, but you and I have all the tools to start out on a much smaller scale and go from there.
Or we can always just draw hentai and fund all our creative pursuits without worry.
