Choosing where taxes are invested… implies someone is doing the taxing

Yes, but it doesn't have to be another human, it can be an incorruptible system. I'm not saying it's easy, most won't even try to understand what I've stated and will accuse me of FED Just like Satoshi created a free currency maybe someone will be able to put together the technological pieces that allow that system. And with that imaginary incorruptible system, taxes themselves wouldn't be the problem, that's where I wanted to get to. I imagine that in such a system the tax burden would be really low and we would finance the most basic and necessary goods for society. I think Bitcoin is perhaps the first founding stone of such a system.
