If RVN keeps going up won’t creating assets become prohibitively expensive?

I'm new to crypto currency in general so maybe I'm missing something but burning 500 RVN to create an asset when its worth $0.15 might not be that big of a deal but what about when/if it's $1? $5? $10? It seems like Ravencoin's main use case becomes less desirable the more valuable the coin is. What am I missing?
