Not every meal is gourmet, sometimes you just need fuel. Additionally, some people don't really care about food as a pleasure to begin with.
Personally, I have a bottle of Soylent maybe once a week when I'm too lazy to make anything else, and I have a soylent bar a couple times a week at my desk when I need a snack but don't want to resort to a candy bar from the vending machine. A Soylent bar is 250 calories and has a reasonably good balance of macro and micronutrients, a Snickers bar is 215 calories and has an abundance of sugar.
I expect that there are relatively few people who consume Soylent as the majority of their calories. Besides, it's not like most people are eating meticulously balanced diets to begin with, so the "long term effects" point seems fairly moot to me.
