Probably because this isn't a new take, we've all heard the same theory many times before. Right now transaction fees are in the pennies. If the price goes up, maybe they'll become tens of pennies or even dollars--I don't think that's a deal-breaker. You should also take into account the lightning network. Transaction fees will have to grow in the coming decades, but if most users stay on LN they won't be directly exposed to those fees.
