They was pushed for a reason: we need to be able to detach from nature for space exploration, we might need to detach from nature to keep living in changed climate where some places are simply too hot, cold etc to live well and so on. Being able to be self-reliant meant being resilient and so being able to evolve more. Of course it's a failure because we are decades behind the needed level of tech and cheap energy to makes such approach feasible and probably they will never scale anyway. But for many aspects they are tempting for many people. Robotic industries like them, service industries like them, some long-term sociopolitical planners like them and so on.
