It's misogynistic because it commodifies women. Having a woman to talk to is something that you can just buy, like a car or a nice meal. They're not treated as people, just as consummables.
A programmer spent a lot of time honing their craft, faces every day challenges, has growth opportunities, can aspire to higher salaries through tough work, has growth opportunities, can influence the world around them and create new things. Coding yields power.
While modelling may require difficult labour, it's mostly just "congratulations for your face".
It's not about whether it is difficult or not, it is more about what type of culture do such things foster and what values does it signal (referring to "SV roller skate models").
Not only does it not commodify women, you're assumption that men will treat them as objects is possibly bigoted.
Men having polite conversations with women is 'wrong' only in a dystopian future.
I personally think it's a little ridiculous and would not want to attend, nor would I put together a party like that, but it's a matter of social taste, not morality.
