Sure it would. If baby formula were unregulated the price would be lower - this is obvious on its face. It would also (probably) be riskier, and the trade-off might not be worth it, but it would be cheaper.

We systematically underestimate how much poverty is worsened by regulation that increase the prices and/or reduces the availability of goods. The left has finally gotten religion here on housing ("YIMBY" just means "deregulate construction in order to drive down prices") so maybe there's hope.
