It's unfortunate that you have a problem with people recommending the method of learning that has been proven to be the safest, most successful, and in the long run, cheapest. When a better method comes along, I'm sure you'll see people endorsing it. Until then, it's reasonable to expect that many will continue to recommend what works.
Until he clarified things in his second post, it was not known that he had contacted an instructor. All people knew is he bought a 3D foamie and proved to himself that he couldn't fly it. Given this limited information, suggestions that he get an instructor, and a trainer plane, were appropriate. Would it have been better for people to just say "get another one" so he could break that one too? Perhaps he should just go ahead and place a bulk order for a dozen?
Crashing due to trying to learn on one's own, makes many people quit. It also wastes money and time. The days of having to be a pioneer and learn on one's own are long past. My first crash did not happen until my second plane, shot down by someone else with the same frequency. Learning on one's own almost always involves a cycle of crash, buy replacement parts, repair, crash again, etc. Eventually, some make it, while many (most?) others quit. It doesn't have to be that way.
