He has made billions using twitter spamming Tesla and doge. It’s a playground for for the guy. And therefore cheap at almost any price. But of course why pay more than needed.

VTOL rockets since no infrastructure
Methane due to atmospheric constraints
Tunnels for transport see also infrastructure
Starlink see also infrastructure
Direct democracy via twitter ( imperator status exempt )
