Going by the BCH community's thinking, the same as Satoshis, the fees will eventually be enough by increasing in number rather than individual amounts and by the market pricing in any changes.

If you don't think this will work, the BTC community has instead moved towards developers actively planning a transition, which was attempted with questionable results as transactions had to be delayed, the individual fee amounts rose to prohibitive levels and even hyperdeflation triggered from which users lost but HODLers won when the fees temporarily collapsed again.
