Right now there are 721 pokemon, plus whatever Sun and Moon brings.
A pokemon may have either one or two types. With the current 18 types system, there are 324 possible ways to assign types to pokemon.
Add to that the Special and Physical split, and the combination of 621 Moves there exist, and the answer is obvious.
Adding more moves would not fuck up the game at all. It would only help the game grow, as more options become available. An alternative would be adding more pokemon slots. Either of these would improve the game.
