why could gravity not be the result of inflation?

Since you are discussing the inflationary model the opposite is true. Read the following discussion by Alan Guth
Excerpt to tantalize the readers:
"According to general relativity, however, there is a gravitational effect which is very important under these circumstances. Pressures, like energy densities, create gravitational fields, and in particular a positive pressure creates an attractive gravitational field. The negative pressure of
the false vacuum, therefore, creates a repulsive gravitational field, which is the driving force behind inflation."
I really enjoy reading Alan Guth. He's so easy to read and the subject matter [cosmology] is just so fascinating. His book "The Inflationary Universe" is a wonderful story about the discovery of a great physics model and a treatise on the history of modern cosmology. I hope that he and Linde get a Nobel some day.
