I see the block size (and frequency) as much as economic rules as the total number of coin is.  I disagree with Satoshi that it is just something that we can 'change.'

I'm part of that sticky group of people that WILL NOT accept a larger block size.  I doesn't matter what other people say; or the reasons that they give.  Frankly, I would reject (with my full node, and SPV nodes) any non-bitcoin chain.  Any block breaking the 1mb/10min avg limit will not be a bitcoin for me.


However I am not worried.  I know that Bitcoin will be just fine with a 1mb block limit; as MarkM so eloquently put is, we need to get over having only one chain, but rarther think of having a ecosystem of hundreds of merge-mined chains that all fullfill different roles.


One of the reasons, (there are many), that I work on Open Transactions is that I believe that we need secure and cryptographically auditable off-chain transactions.  Making the need for more than 7tx/s on the Bitcoin block chain much (completely?) negated.

The best part is that I am in control of this problem.  Even if every other person moves to larger (or more frequent) blocks, I know my bitcoins are safe, and for-me bitcoin will keep-on working. (well other than the attack of a drastic lower hash-rate maybe)

So yes, I think that there is AT LEAST a key 10% of the Bitcoin user population (including me) that will veto any such changes.
