Remarkable things are scarce. That’s why they are remarkable. If everything that everyone does meets the criteria of remarkableness, then it has become a standard.
Scarcity is a result. Not a reason.
When someone chases the title of “the only one in town” or “the first in the region”, you rarely notice or care about them. Just as being remarkable means it has to be remarked upon by their audience (not them), so goes the scarcity.
