That's a great argument if it required a shuttle launch at 1.5 billion a pop. But modern rockets like Starship are a lot cheaper. Musk's $2 million number is probably horseshit but according to David Todd, the Seradata satellite market analyst, Starship launch cost could come in at $10 million. I'd say $10 million to bring Hubble home is worth it.
