I'm probably in the minority on these boards, so call me crazy: I want my currency backed by the economic and military might of the state.
To me, "money" is a means of performing transactions and acquiring real assets. I don't need a hunk of metal or a fancy digital wallet that is "unreproducible" to do that. Being able to print money is a feature of the system, not a detriment. The current system works well enough for me, for now.
You realize that this means you're actively supporting murder, surveillance, and debt slavery built on the backs of the unborn, right? Sure it's easier to just go with the status quo currency flow, but that doesn't make it the most ethical or moral choice.
None of these things are unique to fiat currency, as distinct from capitalism as a whole.
We're only partway out of that crisis, and it could come roaring back. Chest-thumping about "Where else ya gonna go?" is unproductive.
I don't see US hegemony as good or evil, except if you call brittleness that could lead to a very deep unprecedented crisis "evil."
If you have a job, the government will mandate that you get paid in "real money" and it will demand its not-inconsiderable cut in taxes. You want to buy some food? Ok, buy it in bitcoin, but give us our 8% sales tax in "real money". Property tax on your house? That's 3% of assessed value, "real money" only. Etc.
As one pundit tweeted: "You know what's cooler than a million dollars? Virtual currency backed by nothing and nobody."
So, yes, it is that radical... and the suggestion betrays an immature understanding of what currency is.
In the rest of the world, most people don't know about Bitcoin, most of the people who know don't care, and a fraction that I won't try to estimate care but dislike it.
It makes no sense to expect a mention of cryptocurrency in every article about currency.
