Yes, this is the best argument in favor of air cooling. Air cooling has less points of failure.

With water cooling there's tons of potential problems that "haha wind go brrrr cooling" just doesn't produce: Water block gummed up with mold? Take a performance hit. Pump dead? Sucks to be you. Leak in the system? Enjoy replacing your motherboard.

Main issue you might encounter in air cooling is just "fan died, replace fan". (Obviously not counting thermal interface materials since they are required for both cooling solutions)
