I understand if i have a small mining rig and i only make lets say 0.001 BTC a day is maybe not much now but when the price is 50k/BTC this is a lot isnt it?
The rig (I hope you meant ASIC, else you can get from faucets more than from mining) costs money.
The electricity costs money.
People compare the bitcoin price and electricity price NOW, not in the future.
If you want to make profit, it's cheaper to buy than to mine, because the mining costs money (what I wrote at start).
And that's why mining is not profitable.
If you compare apples with oranges, the result will be always confusing. And that's what you did.
