I kind of have a counter to that and thank God it's Nostr, I now have the characters needed!
The consumption rate of gold mining is not uniform. You are correct that on the microscopic level of "now" doubling the energy in doubles the gold out (albeit there is the effort of time needed to get those up and running that I will ignore).
However there is still only a capped amount of gold within the sphere of "Earth". To say this "tends to infinity" because the halving period of gold is extreeeemely long is a misrepresentation at best and an outright lie at worst. It is capped. The double rate of today WILL be compensated by the fact that the halving period will shorten, we will see that rate drop quicker at some future.
Now if you want to argue that you are only living in the "here and now" then you are not really a Bitcoiner, so you MUST consider the infinite timeline and realise that gold-mining (bar the silly Asteroid use case), although it doesn't have a linear inflation rate DOES still have a rate that WILL at some point in the very distant future decline. As miners have to dig deeper, they will eventually dig less each day. However it doesn't halve in four years. Nobody said it had to.
Disclaimer 1: I am not a gold bug AT ALL, I will never buy it for other obvious reasons.
Disclaimer 2: I did not read the original article, I jumped into this reply on my timeline to which i am replying.
So although you are correct in the microscopic yet only theoretical use of "now" when you stretch the timeline to the entirety of all gold mining both assets behave similarly, gold being volatile and unpredictable: yes but declining nevertheless.
These thoughts are my own and I invite them to be taken down. Debate beeth the food of thought!
