There's a real point in that statement, but it's overstated, like saying a University sells you your own brain and community back to you. Sure, you can be an autodidact and get quite an education at the library, you might even be able to find one way or another to rub elbows with the members of a community if it didn't host a university, but a good University will facilitate both at a level

Of course, there's for-profit colleges which provide terrible value at an outrageous cost, and even among "legit" universities or courses of study have more value than others. And back at the topic there's real questions about a church that's acquired assets on the scale the LDS church has. What transparency obligations does it have to the membership that contributed those funds? Should there be dues/tithing, or show the assets function as an endowment to support the activities of the institution while mitigating what members are asked to contribute? If an institution claims divine authority and also reaches the point where it no longer requires contributions in order to sustain it, does that mean it can be more careless with the confidence of those members (and if not, what would prevent that)?
