Fighting hard isn't en end in itself. We'd have idiots fighting to the bitter end for cruft they happen to be personally invested in. It's really about taking responsibility for all the consequences of your decisions seriously.
Idiots fighting to the bitter end is a large part of what molds society today, unless I have severely missed something. Please educate me if I have.
I'm not sure "it's" really about taking responsibility for all the consequences of your decisions seriously, as much as it is creating the space and mechanisms for your ideas to come to fruition. We cannot "see" the consequences of our actions, but we can create systems that stabilize the world. Perhaps this is what you're talking about?
