If you want to frequently get off your bike and walk around, I see the advantages of platform pedals. But I ride to work, and then ride home. If your clipless pedals are causing stress injuries, then they are poorly adjusted.

In the end, I think have dropped handlebars is fantastic, but others prefer a MTB set up. I prefer carrying a Topeak pump for flats, others prefer CO2. If riding with platform pedals makes cycling more convenient for you, go for it.
