So is whisky. Life isn’t worth living if you can’t enjoy it. Kale juice might be good for the physical health, but who wants to live in a world without Coca Cola and ice cream? What’s the point of living a long life if you can’t have any fun?
I find your post to be aggressive and prescriptive, while the post you replied to is just attempting to state fact.
>he point is that in my culture, ice cream and Coke are not “good” for you, but they make many people happy.
If the point is that vices can do more good than harm, you can say that. You don't have to use phrasing which suggests life would be valueless without those specific vices. The inflexibility is that not even your own life would be valueless if you lost them: you could easily find other vices to amuse yourself by.
