With the likes of SpaceX being around, is it not possible to have a store of fuel in orbit, so that these missions can pick a tank or two of them, slingshot their way and use the fuel to speed up the journey?

Or, is it purely economics at play?

It's been possible since the first orbital dockings in the 60s, but nobody's really found the levels of effort and costs to be practical.

Starship will be able to refuel in orbit. It’s actually a requirement for HLS to work, so I guess they’re pretty serious about that capability.
