[The Witcher 3] In the Witcher world, dangerous monsters are practically a part of life, so why don't more people carry silver weapons?

I would always hear people comment on Geralt's silver sword like its an oddity and yet, live literally a couple of meters from a necker nest. Shouldn't more people be more aware of Silver weapons?

The monster density is a gameplay mechanic. In the novels monsters are on the verge of extinction and a common theme is how broke Geralt is because there aren't as many jobs available (not to mention ungrateful townsfolk trying to stiff him).

In addition Witchers themselves are a dying breed and have faded almost to legend in some parts of the world, a common peasant might not be aware of any of the specifics of the Witcher's trade.

Lastly, a silver coated blade is incredibly expensive and useless for fighting a mundane target. Another common theme of the novels (and the game itself) is that humans are a far bigger threat to one another than the monsters were.
