The Cost of Spell Components

I feel like most of the spell components that are hard to get are just, it's just cost. It's just so you don't make a simulate or a 50 dollars. Yeah. Unless, again, unless as part of your game. But there are some like alarm needs a tiny bell and I would be okay with a DM being like, we got to get you that tiny bell. There are some that are a little more rarer than others such as withered vine which is something found in nature. That makes sense if you've been walking through the forest. Whereas beast bond is bit of fur wrapped in cloth. Just pull out your own hair. You just go to the movie
