The universe in question is one in which the Solar System has been colonized thanks to the perfection of a nuclear fusion reactor that doubles as a high-thrust and high-efficiency hydrogen engine. Mars as well as all of the Jovian, Saturnian, Uranian, and Neptunian moons have been colonized either on the surface or in orbit, and a station exists below Mercury's orbit that has a solar-powered superlaser that it uses to perform long-range spectroscopy on the asteroid belt to search for resource-rich asteroids. Also, cybernetics and functional mind uploading using nanotechnological replacement of brain tissue have been perfected, and low-g or quality-of-life enhancements are common, plus completely cybernetic bodies that you can have your mind uploaded into or that you can remotely control using a VR-like interface.
Naturally, someone had the bright idea to set up a bunch of space sports, namely shipracing, involving using as little fuel as possible flying past all of Jupiter's moons without refueling; they can use gravity assists and orbit around a moon for a bit if they need to, and it's likely that a single race would take several days, but the prize money is very good for just intermittently burning to accelerate towards a different moon and then just playing board games and watching the leaderboards in the time between moons. Then, much later once the respective space agencies let the outer colonies have greater self-control, the slightly-less-sane among the mining colonies on the outer planets' moons decided "hey, what if we set up fight-to-the-death sports in zero-g with cybernetic bodies so nobody dies?" So the participants in these "death" games load their minds into cybernetic bodies equipped with high-power RCS thrusters and given weapons and simply instructed to destroy as many other cyborgs as possible until they get destroyed themselves, getting more and more prize money for each "kill".
Here's my issue: what kind of regulation applies to these sports? More specifically, since the colonists want to keep these sports as legal and as unobstructed by bureaucracy as possible, what do they have to do to ensure that these sports are legal in major world powers like the USA, the EU countries, China, etc. and don't get shut down over safety issues or doing stuff that's straight-up illegal?
