This is a very insightful piece (typical of this author).<p>One inherent limit does exist, though, concerning startups that get VC funding. A routine provision concerning the "information rights" that VC investors insist upon receiving states that the company shall provide periodic financials in accordance with GAAP.

Not that this is bad in itself, but it is a fact of life for such companies.
