If your goal is to win money later, playing for pennies (NL $2) is fine. Even at much higher levels, much of your profit will come from recognizing a few bad players with styles you learned to exploit while playing for pennies, and from not making mistakes you can eliminate from your game at NL $2.

At NL $2, there is a much wider range of win rates possible. You can win or lose 50 big blinds/100 hands. This wide range means that it takes much less time for improvements in your game to be reflected in your results.

Just don't get stuck there. Move up when you are crushing the game.
