The reason this advice is bizarre is that old memory isn't actually that dear. The machines that would have had 2GB of RAM or less would be from the Core 2 Duo era or so, taking DDR2 or DDR3, and typically supported 8-16GB. 8GB of DDR3 is currently in the ballpark of $10 and the machines that take it can be found by the pallet in the "free e-waste" pile, so who is going to suffer <2GB instead of 8GB over $10?
