This is kind of a circular definition. When you get this broad with your definition of value/payment, basically what you're saying is that work is meaningful if you derive meaning and/or personal value from it. Which, sure, I agree with that.
But that doesn't mean it'll be monetizable in the traditional sense, and it doesn't mean that traditional employment is the only place to get that value. Many of the things you're talking about aren't representable in dollar form, and it's not clear to me how decoupling income from traditional jobs would mean that those activities would stop being meaningful. Certainly, a lot of those activities are already activities that you can't really make money off of (or at least the vast majority of people engaged in those activities can't).
