You can't discount the filtering mechanism of Y-combinator that easily ups the valuations of the companies that participate and later seek funding. I'm sure the 2-10% equity stake is largely made up for because of this. Edit: If there were many more accelerators, they wouldn't all have the same degree of filtering, and thus the valuations companies would get wouldn't be as inflated. It wouldn't be justifiable long-term.
