Good points, @dracoplato. That's what I was thinking. I've been doing webcomics for... 12 years. At first it was like yelling into a void. If you were lucky people would maybe find you. I was on keenspace, praying to get enough traffic so that I could move up to keenspot (with the potential to get paid). That site is now comic genesis. If there was a traditional model then, I sure don't know it. Things have changed a lot in the past few years! The way I promo/market and make money off my second comic (current)... well, it's actually feasible now. I probably made two dollars total off my first one.
At the time I was just grateful I could put my comic online and didn't have to publish traditionally. But then, I have the same realization as @keii4ii ... maybe I just sucked! (Very likely I just sucked.)
I do think that sites that can generate income and pay creators via ad revenue, or based on traffic, etc is going in the right direction, though I am not sure if it's sustainable yet. Does anyone know any that work? I know that some creators pulled in a primary income from sites like Inkblazers, like that was basically their job.
Kickstarters and Patreon can help Indie creators see their work come into print when it otherwise would've been impossible. Kickstarters are not easily undertaken; do them only if you treat your work very professionally already, and do your research. I agree with @kpalmarin on patreon: Obviously not everyone is successful via patreon and it can be a bit of a headache trying to make it work, but it is very possible to make a good income, or even supplemental income through it. These things can work. A thousand drops in a bucket.
