Sure, and this is a balance that happens in every sector. I'm just pointing out that there's obviously a balancing act between what you can demand from companies in regulation, and what will push them far enough to make them nonviable. Increasing cost doesn't necessarily mean that people will choose to pay it, or that it won't cause uncomfortable disruptions to lifestyle/planning. On the other side, there's plenty of services we want to exist that we regulate, but also subsidize because we think the value of them existing is high enough even if they're not financially viable at the cost we'd need them to be at.
