That is far more effort than what it takes to create FRNs. I don't mean to imply that bitcoins are as good as gold but at least they have some value. If anything they represent the value of the infrastructure. FRNs have negative worth!
I have little interest in gold as a currency either, so being “good as gold” would just make it another investment in my mind. I realize that gold has been around a long time and people have irrationally treated it as a valuable and transferable asset.
