"Introversion" doesn't mean not doing these things, nor being unable to do them. It's about preference and perception.

I never said that.

Being introverted makes it harder to do these things, because they don't come naturally.

They may very well come naturally (they do for me), but they carry a cost that must be repaid later with some alone time (they do for me).
