This is the problem between US vs Europe. Your opinion would be completely moot in the US, which is by far the biggest market at the moment for aircraft like that.
In the US AVGAS is what you want to burn because it is cheap and available. A plane only accepting MOGAS without penalties to the service interval is a non-starter from the get-go. MOGAS simply isn't available in most airports in the US.
C42 is a nice little plane which is unsuitable for heavy-duty training (nosewheel!).
C152, Rotax for Europe, O235 for the US. Perfecto.
