I actually agree completely with that; my initial reply doesn't quite put the focus where it needs to be. So let me try again: in my view, you shouldn't think of policies or laws impacting real people by ever placing yourself outside of the reality in an ideal case, because the hard bit is not conjuring ideals but finding a way of making them happen. It's always a lot messier where the rubber meets the road. People have already died and suffered because ideals (specifically around asset ownership) that weren't quite thought through, but caught on. Take communism as an example. Part of my point is that such "implementation details" are not as unrelated to the central argument as they seem. This is very different from the software world where it might be ok to assume that in 2 years we'll have the computations be 10x as fast and work out a solution backwards from there.
