Mike: the blockchain is a public document, with a very public and well defined interpretation, which we've all signed up for too. What's the point of piling PoW on top of some data to make it difficult to modify if the interpretation itself is open to modification? There is an important distinction to draw between a hard fork via a change in block validation rules, and a hard fork via a change in the /interpretation of the blockchain itself/. Bitcoin validates data /before/ it makes it into a block; we can all be confident that, short of a reorg, /if it's in a block, it's the law/. As much as the 21m cap is the law anyway. Proving that you can convince the economic majority that the interpretation of existing blocks is in any way up for grabs would set a dangerous precedent, and shake some people's faith in Bitcoin's overall robustness and security (well, mine anyway.)
