Jorge will answer for himself, but you know that saying "9MB is also
safe if 8MB is" blows your position.

Do you, or me, or XT know that 8MB is "safe"? You say 9MB must then
also be "safe" - there has been no fact for me to grasp and from which
to tell a Bitcoin trading whale group: "here's the bottom line: this
is what it means and these are the implications." They hold
significant amounts of bitcoin and want to see a plan, and a strategy
based on facts. I can assure you, they're not going to XT, it lacks
both a strategy and the seasoned developers present here.

You're articulate and you raise valid issues, but your judgment of
"safer" is not based on anything you or this list can refer to as a

It seems you want 8MB for some ideological reason but if you examine
your motive and compare it to the facts, you'll find that many people
in this list are ultimately correct in saying that:

Whatever blocksize is set to, demand will soon fill it.

This is the nature of resource supply inflation - some business plan
will spot the opportunity and exploit it, colonize it and then we deal
with that, with some big-girls'-blouses exclaiming: "if we don't give
them what they want they're all going to leave to XT or ZT!"

Even though XT and ZT perfectly fulfill the needs of certain ambitious
businesses, the creators would rather see it happen on Core's
blockchain. Else why do they still come posit arguments here?

Fortunately, unlike the principle that applies in finance capital,
Bitcoin capacity supply doesn't have be increased on demand (not
without rigorous testing and evaluation) plus there is no maxim here
that "the customer is always right". The maxim is "be your own bank" -
during some periods it might be a slow bank but it _will_ remain
decentralized and it _will_ remain your own - not compromised to some
big business or mining cartel.

We want to compromise to science and reason, not profit motive or
democratic lobbying, right?
