Nothing wrong with that, if your diet allows for the higher fat content and it makes you happy. I’m certainly not going to judge when I have bought heavy whipping cream on multiple occasions for likely the same hedonistic, vaguely taboo, reason.

However, despite having advanced tastes, we are well in the minority. Most people find the mouthfeel alone (by alone I mean without enhancing the flavor) to be… mildly unpleasant. And I sort of get that; we don’t have many super creamy drinks, and the ones we do have are wicked rich/sweet. Whipping cream doesn’t taste like much, in the traditional sense, it’s just more expensive and a higher calorie load, and gives you more phlegm, so most people aren’t going to want it outside of cooking where the lack makes a notable difference. Same with half and half; it’s an ingredient and not a food itself.

If you get something out of the mouthfeel and richer flavor that makes it worth it for you, though, you do you. I totally get it. The richness combined with lactose, instead of sucrose or fructose which are harder on my gut bacteria, is deeply satisfying to me, and always has been.
