By the time we're sufficiently advanced to quantum tunnel data or are establishing miniature wormholes for FTL transmission, is it not likely the whole concept of money is outdated by then?
I am not sure the concept of money can become outdated? Even if we live in an egalitarian utopia, there will still be reasons to put value on things for accounting and making decisions and stuff.
Not if we have a Molecular Assembler, there won't be. And I'm reasonably sure we'll get that before FTL.
Time is still finite, so if you want other people to do things for you then you will have to pay them. There is more to life than just stuff.
And won't you need to buy power and raw materials for your molecular assembler to run on?
Well, you'll need a virtually inexhaustible free power supply anyways for the whole wormhole thing. For raw materials you just shovel sand and crap in there. Grab an asteroid or two if you absolutely need some specific elements.
