"But let me tell you what happens when regulations go too far, when they seem to exist only for the purpose of justifying the existence of a regulator. It kills the people trying to start a business"

This quote by Marco Rubio is referring to the threats of over-regulation. When regulations end up being too restrictive, they can stifle the growth of companies and prevent business owners from starting brand-new endeavors. This can have a negative influence on the economy, as businesses are unable to create jobs and generate wealth. Additionally, when regulations are too limiting, they can produce an environment of uncertainty and worry, which can prevent people from taking risks and starting companies. Ultimately, when policies go too far, they can have a harmful result on the economy and the people attempting to start an organization.
