> the general idea that a life spent alone, consuming pornography all day is unfulfilling should not be controversial
1). I don't see why that's not controversial. It doesn't seem self-evident. If a person can fulfill the need by watching porn, then by definition, it is fulfilled. If a person finds it unfulfilling, well, such a person will be motivated to branch out and start doing something else.
2). OP claimed that regardless of whether you watch it all day for a few times a week, porn hinders you down from pursuing females. I'd argue that the latter doesn't.
3). Not forming a family doesn't mean a life spent alone. The only people I know who's determined to not ever get married, has a very active sex life and parties all the time. The idea that one can't be happy without a family is fairly outdated.
4). Addiction is a real thing, but one has to recognize that there is a wide gap between pathologically addicted to porn, and just enjoying watching porn.
