Increasing the supply of gold still comes at a great cost but, yes, bitcoin shines in the area od scarcity.

One area where gold (and silver) shines is in the physical realm without the need for an internet connection. Bitcoin naturaly dominates in the digital realm.

The point being is that they can both be useful tools due to their unique properties and there is no "either/or".

For example, smaller, in-person transactions can be handled with silver which is a true bearer instrument that is untraceable cash with no need for connectivity.

Small, onchain bitcoin transactions have higher cost while Layer 2 solutions require connectivity and/or rely on trusted third parties that can rug you or leak transaction data.

Also, it's nice to have a physical bearer asset to trade with when your cell phone battery dies
