> Do you think the existence of these older cheaper planes is holding back the development of upstart companies aiming for a price point that's closer to the Cessna 172 than the SR22?

Things in aviation are incredibly expensive because of how much it costs to have things certified by the FAA for safety and reliability. I'm no legal expert but I don't think an upstart company has much wiggle room to get around that if they want to legally sell their aircraft in the US. As an example Cessna 172s are still made and AFAIK the modern ones haven't required leaded fuel for some time. A 172 is just about the most basic small airplane you can get but today a new one costs as much as a house, about $400k.
