Because 90 days is long enough to see results for most people, but not so long that it's an impossible time frame.
Because drinking 10 lbs of vegetables is doable, but eating them is almost impossible raw. If you cook them, it's still hard to eat 10 lbs of vegetables and you've killed a lot of nutrients. Because it gives your body a break from digestion.
You'll feel a lot better.
Edit: even those that think the idea of vegetable juice curing anything is goofy basically have to admit that it forces you to avoid process junk for 90 days, and 'eat' tons of vegetables only. Which in itself is bound to fix a decent amount of things bothering people. You could argue that someone could just eat the vegetables, but it's very hard to get 1000-1500 calories just eating (chewing) raw vegetables. So juice them for 90 days. You won't feel too weak, and you'll give your body a break from digestion and from processed garbage.
