There is nothing wrong with being a nit, it is just that people make their money in different ways in this game. Nits often play 8+ tables and play very straightforward, grinding on the fish who don't know the fundamentals. Such a nit will not be able to play profitably against all players at the table.

Looser players often play fewer tables and deviate more from the straightforward/tight style because they have better reads and often better postflop skills. They can make better decisions so they can play more hands. These players are able to play profitably against the whole table (assuming there isn't a better player around and the nits don't adjust well), and they are backing more marginal but +EV bets, so they are able to achieve higher winrates.

I'd say a nit is VPIP below 16 is pretty nitty in todays loose games. But of course, there is no absolute number for a nit. LAG 22+/20+ maybe.
