Small planes are used for much more than hobbyist uses. Prior to G100UL there were no drop in replacements which made adoption of unleaded avgas fuels impractical. G100UL can be manufactured at the existing avgas plants, stored and transported in the existing avgas infrastructure, and even mixed with leaded avgas. Banning unleaded fuel without a replacement would have been heavy handed and short sighted. The government should be working with industry partners to develop a suitable replacement -- as G100UL was -- and subsidize the fuel costs to make the more expensive replacement the same cost as leaded fuel.
