These are real pain points, and part of why I was very excited about crypto circa 2017-2018. It's been five years now, and the builders in the web3 community seem to have stagnated on this, taking a wide tangent into digital art, online clout, and ponzi schemes. The currencies themselves are limited on transaction throughput and trade like traditional risk assets, level 2 networks haven't lived up to their initial hype, and we have come to find that decentralized, immutable currencies are problematic to work with in many situations.
From my viewpoint, it doesn't look like crypto's going to break us out of the local maximum that is central banking/MMT
