While bitcoin might seem inefficient, it is worth comparing it to the systems that it is designed to replace. It would be interesting to calculate how many resources are used to maintain the existing global financial system for a side-by-side comparison. It would also be helpful to factor in other costs for bitcoin besides just mining, such as the resources spent on maintaining exchanges, wallet management services etc.
