I agree, enlightenment can happen many different ways. I see Buddhism as just one collection of strategies to achieve it. But I don't agree that it's obvious. It's so non-obvious that people have been trying to teach it to everyone without charge for 26 centuries without much luck.
It’s obvious in the sense that it’s basically elimination of unproductive habits. And it might be unlikely, but some people arrive there naturally, without pursuing it.
As for the teachings, I think they’ve been misleading people for centuries. Every religion comes up with rules and symbols to explain the “way to the truth” and mostly what happens is they gain a following that just worships and embellishes the symbols. Those people would have been better off being naive. Maybe then they’d be free to have a visceral insight.
