Thats cause wine snobbism is derived from real science and potential skill. Its just that we come from a history of wine knowledge being an upper class thing so imitating it and complimenting someone on their vintage has more social value then accuracy.

We are going to see similar dynamics and boasting with weed but the culture around it is very different. Less “i know more of wine thus my family is of higher standing. I will act friendly but we will never be friends.” and more “everyone hang out with me please, our group passes so much dope as evidenced by my knowledge. Be my friend (But bring your own weed btw)”
