Theres lots to do, like exploring each planet and moon. There won't be any walls to prevent us from devouring every secret Bungie is trying to hide. Doing the raids aren't as easy as you think. ( I hope) Leveling has been made faster in the beta, so you probably won't reach level 8 in two hours. I though we would be going to Mercury, Jupiter's moon, Saturn's moon, and Neptune's moon. Also theres DLCs. Raid armor is not the only cool thing to look forward too. Theres vanguard armor, faction armor. An entire faction quest line. Plus the random events Bungie has planned, for example the Iron Banner, they could make something similar. Theres just so much to do. This is only the beta to give you a sample.
