Ofc, but what better way to make the masses conscious than making them part of it. Also, why do you need the government to limit you before you do something?

- Do you need the government to start issuing flight hour quotas before you start flying less? - Do you need the government to ban short flights before you start using alternative transport methods more? - Do you need the government to impose a high meat tax before you start consuming less?

You can do both, you can start doing your part AND push for political action. Saying "this is meaningless" is just a justification to not do anything yourself and put the blame on someone else. An excuse for inactivity.
