I'm not sure it's a "trick definition". We define nature by observable side effects. You are simply your observable side effects. That's the key difference to the lollipop. Remembrance is not an observable side effect of lollipops. That tree I planted is. That person whose career I helped improve still has an improved career. Etc. That's one of the two ways you live. The other one is the experiences you have. Sure, you can optimize for that, but as far as we all know it pretty much stops when you die. So I prefer option 1.
