You are comparing things of very very different scales. Furthermore, beyond any philosophical questions of 'should man make mountains', the actual proposal here should be attacked on practical and economic grounds. We do not have infinite energy, time, nor finances. Is building a mountain range in Texas so Texans can enjoy mountains really a good idea from that stand point? (not to mention just building mountains of garbage and then covering with soil and rock does not seem like a very good way to build a mountain).
