OP you are very smart, this is the problem that almost everyone never noticed: The fiat money has become the default unit of value domestically

It is so natural to measure value using USD thus people have already get used to it, just like uneducated people always think the sun is going around the earth

The value is all relevant, people will stop using fiat money as unit of value once they had some better unit, I think energy could be the most objective measure of value. Because bitcoin is produced mostly by energy, it is a much more accurate measure of value than fiat money
