Agreed. Only not a near-Earth, but a body just beyond the "snow-line, say 3 to 7 AU away. An object about to be discovered by WISE. Piggy back a methane/LOX rocket onto a Stirling ion drive, say the ASRG, get to a frozen methane/water ice body under Ion drive power and make in situ fuel in inflatable or sub surface tanks. Blast back to Earth L5 with a JAXA solar sail-like shade deployed towards the Sun to prevent sublimation. In less than a decade we will have a gas station in space, with the reasonable "price at the pump" to fund access to fresh water for our fellow human beings on Earth.
Spin and centre of gravity issues will be dealt with by our greatest minds and a lot of processing power. Note that most components are off the shelf, the cost of such a mission can easily be under 2.3B with two launches a year for a few years to replenish the methane and water supply at L5 and improve the initial design. Refuelling capacity at the top of our gravity well is the Holy Grail of future space exploration. This post marks the publication of my intent to make this happen. End Rant. Contact me if you have similar intent.
