That all sounds okay at an individual level, but to affect the massive change we need, relying on moral self-agency is not going to suffice.
So do you want governments to legislate that you must live with your parents? Or that you must not eat meat? Otherwise it's fine and good that a small share of the populace will make these choices on their own, but we need an order of magnitude more.
Carbon tax incentivizes many of my points, but it’s not like my points are the sacred script on what to follow. That and some others do require government legislations (which are a good thing in most cases, and ideally are there to protect and serve the people!), e.g. mandating a standard container, others like living with your parents would need a social change, but that can also be influenced by the government, e.g. much less tax on rent in case of multi-generational homes.
