If only there was an equivalent unregulated food space. Wonder how many crypto enthusiasts would put their money where their mouth is. Or maybe crypto enthusiasts like regulations selectively.
I want a world where I can buy weird powered food from hackers without the man regulating it’s contents.
Frankly, what you want is insane. The reason we have laws and regulations for food content is to avoid killing people with botulism, salmonella, E. coli, lead, mercury, arsenic, cyanide... — basically all the things people used to die of before they got sick of dealing with food-borne illnesses and poisoning and demanded regulations.
The regulations aren't even that onerous. I helped my wife start a food business, and the costs are not anything exorbitant; commercial kitchen space, testing for shelf-stability, and some local certifications. It was profitable enough for someone who is selling as a hobby, but anyone serious would buy or build a kitchen to reduce ongoing costs and boost profit.
Being decentralized is useful insofar that nobody can prevent me for entering into mutually beneficial financial relationships.
"...are of the wrong nationality." not sure what you're trying to imply there but regardless of whether you're investing through a "decentralized" investment system or "traditionally", you're still going to have to abide by the laws of the jurisdiction the company is in.
"...nobody can prevent me for entering into mutually beneficial financial relationships" and nobody can help you if the "mutually beneficial financial relationship" (which is quite a bold thing to imply) is going to turn out to be one way beneficial ;-)
