I can imagine that Vietnamese Buddhist monks of the 60s would share your sentiments. But they, too, could only imagine how much easier it might be. Well, I guess they didn't have to imagine very hard, as it was a lot easier just a few years back. (As background just in case, puppet pro-Catholic government was installed in Vietnam, and the national religion of Buddhism was effectively outlawed, leading at least one monk to set himself on fire in protest.)
I appreciate what you're driving at, I really do as I sit here on my couch in my warm house in one of the most wealthy U. S. suburbs in the country. Easy to do White Guy Suburban Buddhism in that environment. But just because many have it easy doesn't mean it's useless when times are hard.
Except a handful of spiritual gurus who get famous, a overwhelming majority is not surrounded by admirers.
While "appreciating what is" is a great general rule, like any world-view it can be limiting.
I can imagine it's much easier to follow these concepts when you're safely surrounded by admirers. It's probably much harder to walk into a hostile / life-threatening situation and "appreciate what is".
