But space is The Future, The Grand Destiny of Humanity, Literal Heaven.
The mythologization of space as somehow transcendant, that going there somehow changes everything rather than it just being another environment which happens to be utterly inimical to life such that everything that makes anything possible has to come from your point of origin, is so utterly ingrained into the culture at large and the cult of progress/tech/humanity-as-master-of-the-universe. Once you see it you cannot unsee it. And it's incredible how much space SUCKS, such that the people on the ISS are just living off a constant hose of material from Earth. They're not living in space, they're glamping.
But if space was a place that replicators could exist, there would already be an ecology of some sort there. Or to put it in words (that I hate) related to the so-called Fermi paradox (which I hate and isn't a paradox) 'If they could be here they already would be here'. (The 'solution' incidentally is obviously 'interstellar travel is not actually a thing that can happen for replicating systems' and it flabbergasts me that nobody can admit that.)
