Everyone to his own way, all depends where you grew up.

People who grew up in a rural environment tend to be happy on their own, and they tend to experiment more, because they can, and don't tend to sit around waiting for instructions.
Many of these people learn to fly on their own because it gives them a great sense of achievement.
I did this too, - I'm not perfect, and my cheap, soft shelled, scratch built polystyrene power plane crashed a few times ( with hardly any damage ), also I tangled with the prop a couple of times, but I made it ok. and I'm happy!

People who grew up in a city environment tend to be happier with instruction and rules and don't have many problems with them, due to liability laws and the number of people around, ( rightly so ) and so they tend to be more compliant, but we shouldn't try to enforce these rules across the board.

Also there are fliers who like to be competetive, and therefore need a strict set of rules, but do fun fliers who just like to have a nice time flying need to be subject to this strict set of rules?

Some people are perfectionists and spend most of their leisure time getting everything correct and perfect on their aircraft before flying, and others are prepared to accept compromise and spend the maximum time flying something which flies even if it isn't perfect.

So fly sensibly and safely, ( if you are not sure, ask someone who is experinced ) and above all don't let anyone tell you how to enjoy yourself in your own leisure time, there are too many people dying to do this.

Good comment on the rudder, try taking a taildragger off without a rudder!
