There are some people who loathe eating, and derive zero pleasure from their taste sense. They perceive meals as a chore. Those people are their very small target market for the complete-meal-replacement aspect of their product.
Soylent proposes an alternative to cheap $0.50 noodles that is a lot healthier. I know if it was available when I was a college student, it would probably have been in my pantry. I haven't tried Soylent yet, but probably will give it a shot to fill in those meals I can't make due to time constraints.
You are absolutely correct, and I should have been more clear about the complete-meal-replacement aspect. I was referring to the small segment of people that would love to replace every meal with something like Soylent. So maybe "complete-food-replacement" would have conveyed my intended meaning a bit better.
I too ate lots of Ramen in college, but in order to prevent myself from wanting to slit my wrists, I'd usually seek out at least one meal a day with some nutiritional value, and, more importantly, flavor that wasn't just salt water.
