You arenot wrong, all you wrote is simply your opinion. Now factor in that 7 billion people will not have the same opinion about your simple equation of existing gold and existing bitcoin and value.

I will point out some "discussable points" you made.

gold has nearly no value to you, if you need water or food urgently. look into post world war II deals of simple people. why you think?

bitcoin and gold was valued by you against "dollar". why did you do it?

if everyone was looking for an undistored currency, i say bitcoin is the best the world has to offer. everyone knows the rules, everyone know how to mine, everyone knows the cap. no politics involved. no censorship.

yet the whole world is ruled by "people in power" and "politic" and people who simply dont care about "mathematics". now rethink. what happens if not everyone thinks like you? what would be a fair value?
