It's not only the hopefully temporal inconvenience of being replaced. There is a finite amount of resources. If more people have the means to access them, less is available for those who currently consume them. Having 9 billion people sharing the earth will lead to huge improvements in replaceable resources. E.g. movies will be better, appliances will be better, etc. However, if you want to see the Mona Lisa, it's most likely that you will never get close.
