The act of hooking up reduces other people to sex objects to satisfy’s one needs.

One is only trying to get rid of sexual urges and seeing other individuals as a medium for that.

I mean. It kind of feels like you're trying to invalidate the feeling of being desired as something that is valid. In the proper context, aka consent, being desired by another person is actually fun.

One is not trying to make a connection with other humans by hooking up or trying to make a community by hooking up.

As another comment mentioned that is atomization and individualistic.

I'm not surprised to see this. It's also something I encountered in real life with someone. I just think it's a weird hangup. Like, very short term relationships are still relationships with obligations. I bought a homeless person some food on the street. I did not owe that homeless person anything but I had compassion and care for that person. Same thing for a hookup. Just because it's just sex doesn't mean I'm going treat them as disposable. I think it is itself individualistic to think as something that is short term as disposable and not something that still requires care and compassion.
