Re: Bitcoin XT - Officially #REKT (also goes for BIP101 fraud)

And the block size limit has nothing to do with free market, it is just a measure to prevent spam attacks, without this limit, a bank can jam the traffic on bitcoin network for months, so that no transaction can be done at all

I don't think anyone is suggesting that all nodes and miners should be compelled to stop enforcing a block size limit. I think it's more of a question of how that limit should be determined. Should it be decreed by experts in a "top-down" process, or should it emerge naturally through a "bottom-up" process?

Nodes decide the code they run and if there was consensus amongst these peers that the block size should be increased then it would.

Is that not "bottom-up" enough for your liking?

Yes, I agree; that is the spirit behind Bitcoin Unlimited:

"As a foundational principle, we assert that Bitcoin is and should be whatever its users define by the code they run, and the rules they vote for with their hash power." -- Bitcoin Unlimited's Vision

Bitcoin Unlimited is a project designed to make it easier for node operators to exercise their free choice in this regard, so that consensus on issues like the block size limit can more efficiently emerge.
