While government certainly does enable giant chain corporations, I think you are overlooking the more obvious culprit: limited liability. Without the invention of "the corporation" - and the limited liability aspect in particular - nothing like Walmart would have ever scaled to that size. Hell, if all that was holding Walmart back was a common currency, we'd all be using "Wally Bucks" right now.
If the PR renders are anything to go by, you can pretty much take an existing airfield, knock down any ugly buildings that the media might see, and replace them with cool, ultramodern equivalents, and you've got a spaceport.
The distinction between religions that are dead and ones that aren't is certainly relevant; but I do get the impression that some prefer to imagine that 'myths' have always been somehow fundamentally different than 'religions', rather than being different now because some of the 'religions' didn't survive.
The other other point of view is that a uniform means of economic exchange with no additional cost is public service that the government should be doing.
I agree that a common currency is a core government concern. I wasn't advocating that the government should be out of the currency business, just positing that cash usage probably has some correlation to government's interaction with your daily life. There are some pretty large cash payments taking place to avoid taxes, or because the government makes sure it is hard to use credit cards for your illegal transaction.
The other point of view is that cash is needed because the government is still all in our business. Get the government out of the morality game and the cash will more or less disappear on its own. In that way, cash usage is a proxy for government oppression.

Given how lousy the alternatives for appearing to be taking action against the rocket menace are (grovelling through every last hidy-hole in Gaza is militarily doable but a PR debacle and unlikely to turn up more than a few bits and pieces of impoverished machine tools, because low-end rockets just aren't that hard to build. Paying Hezbollah a visit might turn up somewhat more interesting stuff; but that hasn't turned out well in the past) a system that postpones or prevents somebody taking the bait and trying them might be quite helpful.
Last weekend Mars, Ho! passed the magic 40,000 words, the number of words necessary for a science fiction work to be a novel.
