At a certain point, you exceed the ability of the earth to reject heat and the planet becomes venus, though that would take a few more centuries of exponential growth. It isn't crazy to think that there are physical limits to things. Malthus projected that populations would grow exponentially, but agricultural yields would grow linearly. He was wrong in that ag yields did keep up and population growth slowed down. One thing to keep in mind is we used fossil fuels and fertile lands to do that, but we are hitting the limits for fossil fuels and we are burning through arable land. However, there are other physical limits, and some of these are a bit harder to work around. Infinite growth isn't necessary, but a decent life and an equitable distribution of wealth is.
