One of the marks of a good bass sound at a venue is that you feel the low frequencies rather than hear them. If you get your technique and the right settings on a half decent compressor, you can do so without causing ear fatigue.
Headphones can't do this for you so you can't practice how to get there safely at home, you are relying on tweakage at the venue rather than any real experience. With a decent practice amp you can get partway there before you hit the stage, as it were.
