This is the only "argument" ever presented, and I don't think it is any good. I care about file sizes. I want to get the most out of my hardware. Not needing to buy another drive is always going to be cheaper for me and every other user.
128GB+ drives are standard on mid-range laptops. Even at 64GB are you really going to fill up disk space because of Go executables?
CockroachDB (a large software project) is only 123MB. I doubt most people even have 100 pieces of non-default software on their laptop or that executables are going to fill up storage and break anyone's bank these days.
If you're short on HD space, I'm typically targeting photos and videos, not software.
