There are about 210,000,000 kg of gold in the world.
And so, 1 BTC is comparable to 10 Kg of gold.
your comparing money to the illusion of money.
Bitcoin is money and gold is the illusion.
I know what you are trying to say but you misunderstand the energy component of money vs currency and you also misunderstand cryptomining's presumption which is absolutely correct.
MONEY = ENERGY
ENERGY = VALUE
VALUE = MONEY
Gold is intrinsically valuable because of the massive labor energy required to find, extract, and refine it. It is extremely rare and so is a bitcoin. This exactly why mining is required. Without mining, a bitcoin has no stored energy and therefore no stored value.
Both gold and bitcoin operate on the same principles of sound money. They are both stores of value. Gold has been real money for 6000 years. Bitcoin is in its infancy but with more exposure will gain confidence and it turn will gain wider acceptance.
But to call gold an "illusion" is simply ignorant of the basic fundamentals of money theory.
