If it weren’t being pumped I don’t see this being a real issue. With fiat money has some smallest division possible (aka the penny). When there is more money needed the banks print more money and so everyone’s money becomes worth less so we see inflation. With a limited digital currency like BTC you would expect to see deflation and so over time transactions would require a smaller fraction of a coin as payment.
