I know there are ways around such blocks but I don't bother using them. If a site prevents me from seeing its content if im blocking ads I close the page and make a mental note to not click on links to that site anymore.
I probably would stop using that site, I think it's important to support sites that make meaningful progress possible. But again, that doesn't really have any impact on my decision to make sure foreign code doesn't run on my machine.
Patreon is a big step towards fixing that, since it allows me to pay small amounts to people whose work i enjoy very occasionally. It is however not the end game yet, and i think if that path is pursued further, ads can become a part of the past.
Also the "just don't go there" thing is hard to do in reality. If only because to find out that a site is bad, you need to first go there. Then there's the cost of remembering in the future that the site is bad. Then there's the social cost of getting linked to a thing. etc. etc. etc.
Even if the internet had no ads and no tracking code and no malware anywhere whatsoever, there would still be a need for the technology to block and change the way in which my computer handles the things sent to it by other computers before showing them to me. I have a myriad blocks and css modifications and even site additions and other things set up that have absolutely nothing to do with ads, and being able to do that reliably is important.
That is why this matters:
Controlling what my own mechanical device does with the information it receives from other people's machines.
Besides, as i said, i don't even use pornhub.
Heck, a number of sites i use this stuff on are sites where i pay profusely. My steam expenses are 6000$ at this point, and i block a lot of things there, primarily because they actually make it more difficult for me to find the things i want to spend money on.
