Ideally what you would want is for the rocket to land downrange and get sent back up again carrying cargo. However we are far from needing to be able to do that, so the best that we can do is send the rocket back so that we can use it again.
Interesting idea.
So... what... launch from Hawaii, land in New Mexico. Launch from New Mexico land in Florida...?

And extend that then... North West Australia to North East Australia to Hawaii....?

How many launch pads and ground crews is that now...?
And these things are free, right?

Well *technically* at some point you want a world-wide set of spaceports just like airports are for inter-continetal transport... :)

No they aren't "free" but do you REALLY notice the "extra" cost of an airplane/bus/train/ship ticket because the company has servicing and maintenance people/faciltities in more than one "port?"

*Technically* (and I really need to stress this is down in the *technical/theory* realm and PROBABLY has no REAL bearing on any decisions being made...) you gain a lot by not having to perform a "boost-back" manuever but instead using that propellant (or the majority thereof at any rate) to enhance payload-to-orbit performance which will be lacking under the RTLS option. What you have to do (and we can't really do given we don't have the needed data, so we're "speculating" at best) is figure which factors are impacting what are your priority issues.

No matter what as as business you have to establish that meeting "customer/market" priorities/goals is extremely important over and above any priorities/goals you have as a business. RTLS may be a *nice-to-have* goal but I'm going to be highly surpised if SpaceX doesn't put a higher priority on *payload-to-orbit* performance just because that is a higher *priority* with their customers than *payload-to-orbit* price currently.

British physics, old chap. It's undignified to belch flames and effluvia all over the pad, what. A true gentlemen's orbital conveyance lifts itself into the air unostentatiously, with the minimum of spectacle and a modicum of grace. Not like our American cousins' launch vehicles, eh?

Hopscotch the world!

Could explain why the guy who started Google bought one of the Hawaiian islands.  He's decided to build a launch center, (and Mad Scientist lair?) There.
My God!  It's full of universes!

I know that Larry Ellison bought Lanai with the (speculated) intention of doing ecofriendly agriculture.

Which Google co founder, Page or Brin, bought another island, and which one?
