Was going to say this.

As a whole, big corporations tend to embrace some retarded rules as a way to make it harder for new companies to breach the market, essentially creating a monopoly (or more commonly a oligopoly) by way of government issued rules.

The more regulations a business is under the less likely some new upstart can just join the fray. Just send a bit of cash to some politician to convince the others that your type of business needs to get an expensive certificate before they do something and you got yourself a nice higher barrier for entry
