Life is beautiful, but that beauty is diminished by suffering. If not, we should all strive to have as many children as possible while keeping them barely alive. I believe most people would view this as abhorrent.

With that mindset, infinite growth is similarly (if not more) disdainful of human life. It should be obvious that population cannot grow unbounded; at some point growth will lead to austerity. You highlight sustainable growth, implicitly assuming the Earth can continue supporting more people. Understand that many do not hold this view.
