I mean, sure, art has constraints.

My sister likes to work with [checks notes carefully to avoid the wrong words] old textiles. This of course constrains the kind of art she can make. That's the whole point.

I see live coding the same way as the harp, or a loop sampler, an instrument, one of an enormous variety of tools which you might find suits you or not. As performance I actually enjoy live coding far more than most ways to make music, although I thought Amon Tobin's ISAM Live was amazing that's because of the visuals.
