My point was how the Vulcans viewed this. They wanted to help but in reality Earth wasn't any different from before the first warp flight. I think it's surprising they didn't walk out of the ship look around and say "screw this" and get right back in their ship and leave.
I don't really see it that way. Why did the Vulcans come in the first place? Why had they not come before? The reason wasn't Earth's "level of civilicity", it was Earth's ability to travel at warp.
Before warp drive, Earth would have been just another primitive planet on the Vulcans' back yard, perhaps one out of dozens such harmless toddlers. After warp drive, she would become an out-of-control teenager, hell-bent on roaming the neighborhood and getting into all sorts of trouble. Vulcans would feel the need to settle in just to guard their own interests.
And they would guard their interests in a benevolent manner, as dictated by their philosphy and perhaps by earlier experiences as well. The worse these primitive Earthlings, the more they would be in need of benevolent control...
