Space... where anything you destroy turns into chunks that
circle back to deny your own use of those orbits for at least
the average orbital decay period... which for useful orbits more
efficient than lower ones that require economically draining
ongoing replacement launch costs to offset losses to decay,
rapidly becomes greater than 100y... an interesting mutually
assured destruction (MAD). Orbits also can't be enforceably
owned by title, but only by developing technological capacity
to push the safe density on orbit greater than what any
competitor can safely handle without triggering their own MAD.
The only survivable non MAD "human future beyond earth preserving"
space combat would be grappling deorbiter bots that also
deorbit all their own spent rocket stages. But since they're
still filling orbits with spent casings and dead satellites, that
sort of universal human agreement and commitment to space
caretaking is probably still years overshot, just as human
resource consumption on earth is far more overshot.

Starlink is interesting, but in order to be of much use to
humanity to avoid the very censorship control and destruction
it's in the news for routing around in Ukraine... Starlink really
does need to allow fully anonymous purchase, delivery,
and payments... cash, crypto, unserialized retail purchase...
for everyone on the planet. And you're still going to need a
ground based p2p overlay using RF fiber copper since
Starlink can triangulate the dish uplinks of its users.

GovCorp central internet services are just cheap and risky backhaul,
only to be used as overlay distance bridges until you can complete
building your own global encrypted anonymous p2p piecewise
physically owned house-to-house parcel-to-parcel distributed next
generation internet using RF fiber copper GNURadio wifi meshnet,
crowdshared community network building instructable how-to co-ops,
etc.

"Distribute all the things" must now include not only cryptocurrency
and internet services, but the entire notion of the physical internet itself.

 NewmanApril 29, 2022, 1:47 pmUkraine’s plucky military has so far outboxed the 
larger and more muscular Russian army that invaded on Feb. 24. Elon Musk may 
have something to do with it.
"The American punditocracy has obsessed over Musk’s recent deal to purchase 
Twitter, which might ruin free speech as we know it, or, modestly alter a 
social-media platform most Americans don’t even use. Meanwhile, people have 
been dying in Ukraine—or not dying—because of Musk’s effort to help the 
underdog Ukrainians with secure communications.

"On Feb. 26, two days after the Russian invasion began, a top Ukrainian 
official asked Elon Musk on Twitter to activate SpaceX’s Starlink service in 
Ukraine. Starlink is a satellite-based high-speed internet service offered by 
SpaceX, where Musk is CEO, for people who don’t have access to wired internet. 
Airlines may adopt it for in-flight Wi-Fi. SpaceX rockets have so far deployed 
about 2,400 Starlink satellites, with the goal of ultimately fielding 42,000 
satellites that can provide internet service in most inhabited parts of the 
world."
