I actually think it’s fair to consider all of the above, except for Bitcoin, as “unlimited” in their quantity.
You can always build taller buildings and humans forever have been making in habitable places habitable. You can always irradiate and put enough energy into nearby elements to obtain more gold and silver, at great expense yes, but no legitimate limit. Therefore the value of all is explicitly capped and cannot reflect society’s growth and prosperity as a measuring tool.
The only thing with the scarcity and capacity to carry that weight is #Bitcoin
