They argue against car seat requirements by pointing out that they don't work as well for older kids, but it's precisely the lack of requirements that result in booster seats not performing as well. No one makes any that standout as better, because they aren't required to. Likely, you aren't going to get better performance without using a 5 point harness, but the market for something like that would be far to small to maintain, so we don't get a choice. I'm not arguing that we should require 5 point harnesses for 8 year olds, but I am pointing out that we didn't have the option to buy infant car seats, as effective as they are now, before requirements were put in place.
