Sure video games can be unhealthy. Maybe I'm weird but I would much rather prefer my son plays video games 8 hours a day than watches adult content 8 hours a day. Let's stop pretending like they're comparable.

Isn't it the end result that matters? Presumably you'd like your son to become a functional adult. Neither of the scenarios you describe there sound like that to me (excepting perhaps "professional competitive gamer" but somehow I suspect most parents don't really approve of that outcome either).
I guess it comes down to time allocation. If you're spending "a lot" of time on it but not so much that it precludes conducting the rest of your life in a functional manner then why would spending the same amount of time on porn (or any other supposedly degenerate activity) be any different?
What else should we arbitrarily ban based on this criteria? It doesn't seem to hold up to much scrutiny.
