All the Whos in Whoville would beg to differ about them being "rocks waiting for us to do something with them". Flippancy aside, just assuming there is no consequential life on any of those rocks just waiting for use to exploit is quite arrogant of us. I'm fully behind humans being multi-planetary to increase our bus factor and because it's just plain awesome. I also think some caution is needed to prevent us destroying signs of other life before we even know what we've done. But this is not some revelation, smarter people that me have already thought this stuff through. We just have to follow through on the protocols.
