I highyly recommend reading his book and his blog.
Looks interesting. There is a wiki article on it that mentions a couple of problems. The first one I noticed myself is that the creditos they are printing look pretty easy to counterfeit. The other is that it takes some effort to find the goods and services that you may actually need. It’s still fiat money backed by a social contract.
I have seen a suggestion that to help ourselves here that legal tender laws should be suspended allowing the development and use of alternative currencies, possibly backed by something. I’m a little dim on how it would work but I thinking that we are looking at a massive wave of inflation coming.
