Toka,
If gold plating is bad, you better tell every computer manufacturer, hifi manufacturer, connector manufacturer..................... Gold isn't a perfect conductor but that is not it's real mission. The mission is to secure a mechanical slipfit connection a.k.a. a jack and a plug. How many times in the old days has a system problem popped up and with a few wiggles of the wires, it went away. It has been discovered that these small mechanical connectors for all of our equipment is subject to corrosion and oxidation. Gold plating, though not the most perfect conductor, solves this problem. Computers are full of gold in all of their connectors to make them reliable. Until some wiz bang chemist/metalurgist comes up with a new alloy, it's the best we have. I want my stuff to have gold connectors.
