Yes let's stop all scientific and technological progress which isn't directly related to achieving utopia on earth, until a hypothetical point in the future that will never come. Slapstick arguments don't help. The whole point is that none of the proposals offered in the comment above yours are even remotely "utopian". They're all pretty much common sense (or should be by now), actually.
