📝 Original message:Please don't put words into Pieter's mouth. I guarantee you everyone
working on Bitcoin in their heart of hearts would prefer everyone in the
world being able to use the Bitcoin ledger for whatever purpose, if there
were no cost.
But like any real world engineering issue, this is a matter of tradeoffs.
At the extreme it is simply impossible to scale Bitcoin to the terrabyte
sized blocks that would be necessary to service the entire world's
financial transactions. Not without sacrificing entirely the protection of
policy neutrality achieved through decentralization. And as that is
Bitcoin's only advantage over traditional consensus systems, you would have
to wonder what the point of such an endeavor would be.
So *somewhere* you have to draw the line, and transactions below that level
are simply pushed into higher level or off-chain protocols.
The issue, as Pieter and Jorge have been pointing out, is that technical
discussion over where that line should be has been missing from this debate.
