When and where did you get your information? Because this is completely wrong. LSA's and gliders rely on self-certification for the very medical reasons you mentioned. In smaller aircraft where you don't carry passengers and don't fly in demanding circumstances (high speeds, altitudes, IFR, etc), the margin of safety for the general public is much wider. The FAA puts more trust in your own assessment of your medical condition's impact on your safety, since the main person affected by your ADM in such an aircraft is yourself. editing to add that this isn't speculation, I fly gliders.
