I agree with your idea mate. We can't afford to buy things lower than the transaction fee. As we all know fees are getting higher as price skyrocketed and how much more in the future? Are we going to buy candies with Bitcoins high fee? For me Bitcoin is only best for  investments. I think buying goods with Bitcoins has issues with fees more or less four to five dollars per transactions really sucks. People using fiat all the tine are more affected in a cashless society and I don't know how they would adopt most especially less fortunate people with no idea on this blockchain technology. It is hard for these people to embrace such ideas and that is the fact about cashless society. I am one of those less fortunate people but I am lucky enough  because I have now the ideas regarding blockchain technologies and I am happy with that.
