The major benefit of Meteor (at least for me) always was its quick bootstrap. So you want start coding or work on a mock-up? Just meteor create myapp and start. No boilerplate. No script and style tags. Heck, add bootstrap with a single line of command and you start with fine-grained classes! Sure you might need a database... don't worry! No need for schema, modeling, whatever, the server is already there and so the database. Eventually you might want to scale and then, as in any library/framework/platform things will get a little more complicated. I don't see it as a problem, really. Meteor always was opinionated and maybe some opinions were unpopular from the beginning (MongoDB, for example). But when you start adding multiciplity (React/Blaze/Angular for the frontend, Iron Router/Flow Router/React Router for routing, Meteor Package System/NPM...) you can lose the track. I'm afraid this is happening now.
