Sounds like two very good reasons to me (in my very limited experience). I have no hard numbers to back this up (just observation of comments here from other beginners like me), but my suspicion is that way more peeps get started in this hobby on their own or with informal 'support' from (sometimes equally clueless) friends rather than with experienced instructors. Hardly surprising when you can put a beginner suitable plane in the sky for well under $200.
