Back up this single sentence. Point to a single book on physics or math that supports this single sentence.
Ok, but pay attention to ''In the general case''. You can always consider an unnatural situation where the infinite universe isn't homogeneous and only contains a finite number of stars. Such a situation is unnatural from the point of view of basic physics and astronomy, not simply because it doesn't predict an infinite number of observers.

I'll give you some peer reviewed publications:

Joshua Knobe, Ken D. Olum, Alexander Vilenkin,
''Philosophical Implications of Inflationary Cosmology'', to appear in British Journal for the Philosophy of Science, preprint


Ken D. Olum,''Conflict between anthropic reasoning and observation'', Analysis 64, 1 (2004) preprint


This book explains inflation:
