This isn't a very solid post.
It is way too rambling.
You try to point out a problem, but only partially describe it
and then you offer a solution out of left field, while poo-pooing other solutions.
Local currencies work only in certain instances.
That being that they have a local infrastructure and a local supply.
In other words, you can't buy from Wallymart with local currencies.
Further, the problem with local currencies is that they are way easy to counterfeit. And they are very easy to pump and dump. Their only advantage is that they may be so small that why would anyone bother to mess with them.
Crypto-currencies are a great solution to many of the problems you bring up. But, you discounted them immediately.
The thing about local currencies is that cryptos make making local currencies really easy. It also makes them really easy to exchange if you need money to spend elsewhere.
And the biggest thing about cryptos is that you can't print money. (unless you are talking about inflationary cryptos like Tether, Ripple or STEEM.) So, there will only be 21 million bitcoin. If the people behind the FED print lots of money to by bitcoin, the price of bitcoin goes up. And everyone that owns bitcoin gets the reward. Basically, the FED will lose.
We will see The US$ dying here shortly. (mostly because of this very thing)
I willingly take your constructive criticism, and welcome it, I have only started this, and will make a lot more posts to substantiate my thinking, hope you stick along for the ride, as I am always open to debate.
Oh by the by, see what you think regards to this article. https://fpif.org/the-new-world-order-is-here/
