It may not injure you right away, but I do think that it will weaken your support of natural movements. Less importantly, I don't really like the slight counterweight effect, either.
I would submit the smith actually helps you.
I would submit the smith helps you because for many exercises you have to follow a same unaltered path, bench, bent row, military press.
I would submit using a free bar would lead to unbalanced movement ie. right arm pushing more than left and elliptical movements like instead of benching from nipple to up you move from nipple to up to right nipple to left delt to above your neck.
Hence the conclusion is smith is good. Thank you.
