Something being beneficial to a business does not make it broadly necessary, desirable, or - in many cases - legal.

It would be extremely beneficial to businesses to put a clause in their terms and conditions that limit damages to 1 cent in the event of any dispute. For obvious reasons we don't allow anything like that to be enforced.

I'm not saying whether tracking should or shouldn't exist, but "the business can make more money" is not a valid argument in my book.
