That's a non-sequitur. Stone is not considered a renewable resource, which is typically defined as a resource which naturally replenishes itself over time at a meaningful rate compared to the rate of consumption.

My point is that "renewable resource" is a fairly meaningless term when applied to stone. Sure, we technically have a finite amount of it on the planet, but we also can't possibly use it all up. Not unless we have technology that would allow us to travel outside the solar system, at which point the limited amount of stone is also moot.

Sure, it doesn't fit the definition, but there is also no reason to care that it doesn't.

Do we really consume more stone, than gets relenished? Is that a assumption or well studied topic?

It's my assumption based on the fact that we continually mine new portions of the earth over time. Trees and other life exist within regenerative chemical cycles, whereas rock formation is a physical process that consumes some limited supply of material on Earth. I would love to know more about this as well, if you come across any resources.
