> If markets decided today that Bitcoin was a more desirable currency than the Dollar, we would be wiping our asses with the Dollar by mid-day today.
That is the bitcoin game-theoretical endgame.
The dollar system has a ton of momentum, so it might not be quite so fast a transition as you think. People dont have a hive mind and dont all decide everything at once.
A ton of economics comes down to peoples memories of the past impacting their present actions. The only reason people accept dollar prices or values of things today is because they remember recent past prices. All prices are "sticky prices", all wages are "sticky wages". So even if some large contingent of people decided they no longer value the dollar network, it would still have value derived from the people who do value it.
If bitcoin continues to survive, and slowly appreciate vs the dollar network, a breaking point may come wherein that effect accelerates. Money systems follow the "network effect", and so long as bitcoin is not fading towards zero value/use, it remains a contender for a network flipover.
> There is nothing inherently valuable in any currency. Not gold, Dollars, Bitcoin, teeth, or anything else. All currency is printed out of thin air (yes, gold too). Today's currency is tomorrow's toilet paper.
Not quite correct; while no system has "inherent money value" which is fully created by human social behaviors, money system do in fact have attributes and qualities which affect how they do function as money networks.
Gold has a more limited supply, but it is slow to validate and extremely slow to transmit.
The dollar system is quicker to validate and transmit, but has a rapidly growing supply which devalues it against itself.
Bitcoin is a historical first: more transmissible and speed greater than the dollar network, combined with an absolute supply cap even more rigid than that of gold.
Those properties are strong enough to keep it in existence despite the network effect of the dollar. Really the only move the dollar system could make to fight back would be an extended period of non-inflation. That would allow the network effect to re-assert itself by removing bitcoins primary advantage.
It is unlikely the dollar system could sustain a large period of non-expansion, but a short burst of extreme deflation might have a similar effect. If neither of those two things happens, bitcoin will continue to slowly appreciate, eventually leading towards some kind of end-game scenario
