In what way "permissionless"? In the way "the government has agreed that they can be unregulated financial products" or in the way "hopefully it can evade government financial regulation"? or in some other way?
Sure there’s definitely US-centric issues given the current regulations in place.
But it’s permissionless in that if the financial markets don’t support a structured product you or your community needs, you can create and deploy it yourselves with instant global accessibility.
You could (Matt Levine talks about his ExcelCoin he tracks in a spreadsheet), but with the rise of AMMs [1] (and SSOV’s) it’s easier to make the market in the DeFi space.
That feels like saying stealing food is a permissionless new way to get food. And I'm not at all convinced that the governments of the world could not regulate blockchains, or their use, if they wanted - either in ways like outlawing it, or auditing / regulating / taxing companies which use it, or pressuring insurance companies to put limits against insurance cover, or numerous other ways.
