Ok look, I have the solution here, and everybody wins. However I will require from each person wanting to purchase a Cobra 4 the following:
100 gallons of diesel fuel, 14 ounces of refined, enriched Uranium-238, 2 20 pound bottles of compressed hydrogen, and 3 milligrams of anti-hydrogen.
These materials are required to power and operate my time machine, with which I will promptly return you to December 28th, 2014, at which point you can then purchase your Elite: Dangerous account and be eligible to access the Cobra 4.
You will, of course, have to live out the remained of your life in your own past, as I cannot return biological material from the past to the present without creating a fatal temporal paradox.
But at least you’ll have a C4, and Frontier’s glorious reputation will remain intact.
There will come a day, however, when you will suffer an incredible migraine headache, which will be the day you purchased your Elite account, as you will want to carry out this task at that time, but having already done it in your own past your neurons will react to this minor, self-correcting paradox, which will pass when you reconcile having already done what you are trying to do. These migraines typically last for 1 to 2 hours, but are completely debilitating until they pass.
