Online porn would be worth billions of dollars, and not 1 or 2, more like $20 billion to $30 billion.
Sadly the cost of giving it away for free has hurt this business. And will continue to hurt this business. Even Manwin will get hurt. Because free is so cheap to give away free to 100,000s when a sale on anything, will pay for it. And that anything, won't be a porn paysite. Eventually not even the very best. Eventually even micro niches may get hit. Someone will start a Fetish Tube site, if it's not already done. Probably is.
And all the marketing expertise in the world isn't going to change it.
