Because surely you can see that an extra 10 land speed and the ability to rage is a huge benefit? Class balance is very fragile in 3.5 TBH, and IMO it is designed assuming everyone will be a purist with prestige classes thrown in. Allot of classes throw in huge beenfits at lvl 1 that should not be freely accesable to other classes. And seriously how can this be an issue? Why in gods name would you have a halfling barbarian/fight or a elf barbarian/fight the only 2 races that would suffer a penatly for this? I think the rule was designed with the belief it would only effect people who wanted to be a fighter/magic user/thief for example so 3 multi classing!
