Hard disagree. Finding 'water' trapped in glass beads isn't something useful to us. Converting that to potable or even just liquid water will take far more energy than taking that water out of Earth's gravity well using conventional rockets.
The universe is still a harsh, bleak, unforgiving, inhospitable, irradiated wasteland of empty nothingness. Humans need very specific temperatures, air pressures, atmospheric compositions to survive. Humans need food that also needs those things to survive. We can alter extra terrestrial objects to suit our needs, but that costs us energy, materials, and money/time. Right now, we are far too busy chasing fads and trinkets, and bashing in the skulls of our own fellows to be able to manage this.
