Which regulations in particular? All businesses rely on governments not choking them into nonexistence by having regulations that harm that business. Regulations are not an amorphus blob. There are other regulations that would also benefit a business to enable its existence, but we would not say (or should not say) that "the whole business relies on having regulations," because that is being intentionally vague about what the regulations in question actually are. The way you phrase it almost implied there is inherently something dangerous or suspect about something that is universal about how regulations can effect businesses.
