My smug view about lifestyle is that provided you do no harm, do whatever you want- it makes no difference. You will be on this planet for 60 to 100 years and then you will be no longer and nobody will even know that you existed, apart from relatives and friends of course. You will only be remembered if you did something big and history decides to document it: Albert Einstene, Adolf Hitler, Plato, Vincent Van Gogh, Stalin, Henry Ford, Wright Brothers.
And even this minor planet in a minor solar system in a backwater of the galaxy will be gone one day and will be uninhabitable anyway in around 500 thousand years, when the sun expands, if not before that due to some cosmic catastrophe.
But, on the other hand, your lifestyle may not do any good. There are people who contribute to society: miners, doctors, teachers, utility workers, military... and there are those who do not and basically live off society. It does not matter because there are more than enough people out of the world population of 7 billion (corrected) to keep society running.
But what does grate with me is when the people living off society make out that they are saving the world, saving your soul, or even forecasting the future. And even worse, when they impose their views on others and cost society billions.
