For the longest time I tried arguing with my ISP that I only needed around 20Mbit. They did have a 50Mbit at the time, but the price difference between 50, 100 and 250 and meant that you basically got ripped off for anything but the 100Mbit. It's the same now, I can get 300Mbit, but the price difference between 300 and and 500 is to small to be viewed as an actual saving, similar, you can get 1000Mbit, but I don't need it and the price difference is to high.
