"One thing is clear: We won't be using cash in space," Marcus said. "PayPal has already pushed payments into the Internet, onto phones and across terrestrial borders. We look forward to pushing payments from our world to the next, and beyond."

If someone has 'internet in space', why can't they just use Paypal Terrestrial? Or Bitcoin

?
We need Paypal Galactic like we need Paypal Fatburger.
