My clone of bitcoin would have exactly the same properties as bitcoin. Your lead bar doesn't have any of the useful properties of gold (ductability, beauty, conductivity, etc).

Except that your bitcoin won't have exactly the same properties as bitcoin, mainly the miners which do provide network security.

For most applications (including Gold's most popular-by-value applications, -- jewelry and sitting in vaults) you can substitute it with other materials with equivalent (or better!) physical properties.

Except for the massive number of miners securing the existing Bitcoin network and creating the security that is the inherent value of said network.
