You gavincoin people simply won't do the math. There is no realistic point where a decent fraction of the worlds population can use native Bitcoin and have it remain supportable by anything but the most well situated mega-players.
I would ask if you'd change your mind if the math showed you to be wrong, but we already know the answer to that, don't we?
Yup. I'm not interested in theoretical hand-waving base of simplistic assumptions of how computers and systems generally work (and x*y/y=x is unimpressive to me mathematically.)
You (nor anyone else) responded to my simple arithmetic showing we need 10,000 tx/sec or so for less than half the world to use Bitcoin once per day. Show me any example of anything remotely resembling a full scale Bitcoin network even existing in the real world, much less one under any sort of attack, and maybe I'll re-think my position.
Give me one clue about what you are thinking should Bitcoin somehow unexpectedly stop working well after 5,000 tx/sec and why we should put our finger into the Chinese finger-trap to figure out when we need to shift gears.
Nobody wants to address the possibility that governments may wish to clamp down on the solution if it becomes a challenge to them, and play that out to what it might look like.
As I've said before, it I were planning an attack on Bitcoin, I'd to exactly what the gavincoin folks are doing, and I hypothesized about it years ago. I think it very possibly that this is one of the main incentives for trying to introduce exponential growth.
Here's the deal. I do NOT think that it is irrational to consider our 'best bet' to go the direction our leaderships map out for us. It is NOT irrational to trust the democratically elected political and social leaders over a band of often-criminal malcontents who happen to have a disproportionate number of chips at this point in the game. Most people 'love big brother' and I have no reason to think that Gavin and the folks involved with the Bitcoin Foundation are any different. Just the opposite in fact! For that simple reason it does not strike me as especially unlikely that they would like Bitcoin as a solution to be brought to heal and they probably see plenty of legitimate uses for it even when it is. For my part I simply dis-agree with this analysis and see Bitcoin as a pretty boring and useless, and mainly as just stepping stone toward a real solution if they get their way. I'm not ready to give up on Bitcoin just yet.
