Unlocking rune slots should provide flexibility, not power
At pre-30 levels, "locked" rune slots should be auto-filled with AD reds/quints, armor yellows, and MR blues. Those runes should be given out for free so that you don't level up and then effectively lose a rune slot. (Really, all runes should be free, but let's take things one step at a time).
It's a good thing to restrict new players' options. For example, I can play Ashe Jungle by abusing attack speed runes and krug buff; Not having those runes prevents new players from doing that, and that's a good thing. But we shouldn't also decrease their power for it.
Yes, it's true that runes don't matter as much for new players in terms of PVP combat, because how fast you're grasping the game matters so much more. But, for example, not having runes makes last hitting much harder, and that's frustrating for everyone (which is why I suggest AD reds and quints for all champions regardless of their standard runes).
