.... It's almost like you have no idea how the business works in 2019. At all. Your questions are so off base.
Anyways, there's more people shooting more porn today than there ever was even 10 years ago. Likewise, consumption is substantially higher. Supply is at an all-time high as well as demand. This is what happens when markets liberalize.
25 years ago in the US, there were a few major studios with a few major distributors shipping to brick and mortar stores. Of course there was Joe Nobody in Wichita, KS, making a living selling DVD's of him fucking "amateurs" at his apartment, but that hardly made up any significant portion of the industry at the time. By and large, the industry was pretty closed off as far as production and distribution went until the internet became more accessible and prolific.
Today, if a 21 year old chick in Denver can make a decent video of her fucking her hung boyfriend, put it on PH / Modelhub, ManyVids, Clips4sale, then sell her premium Snapchat and Skype shows on the side, she can easily clear mid 6 figures per year in profit. She can make this per month if she's drop dead gorgeous, great performer and great hustler. There are quite a few who do.
At no point did I say that this is the norm for the industry-at-large now. But there's thousands of amateurs doing exactly this, and there's a whole lot of "studio" porn still coming out as well as faux-amateur from those same people - sometimes just under a different corporate umbrella.
Anyways, that PH number for premium views is pretty spot on. I've seen the monthly average be a bit lower and I've seen it be a bit higher. That doesn't mean you'll get the views, though. What does well on the free side usually does well on the premium side also. Hence AdultForce, New Sensations, MadCheddar, PaperStreetCash and Nubiles properties dominating with a few others like JulesJordan doing quite well.
But that's because all of them shoot very good content for today's market. Throwing up some cookie-cutter shit won't do well at all.
Regardless, the industry is substantially larger today especially revenue wise. Just the guys located in Montreal alone (Mindgeek, Gammae, Sex.com / Braincash) make way more money than you offline folks did even in the hayday of DVD. That doesn't include the big companies in the US, like Streamate and Chaturbate, and the massive companies in Europe / Russia.
