Before you can consume wealth, you first have to create wealth. If you have a job, and you are using your own money to pay for the things that you consume, then everything should balance out. There is no need for you to feel guilty. But even if we didn't have so much land, we could grow food indoors. You could have a 50 story skyscraper, and grow food on every floor.
Technology keeps making resources more and more abundant.
As long as you are paying for the things that you are using, there is no reason for you to feel guilty.
