Answer to point 5: On first glance I would agree with this view, however, there is the factor of market competition you must take into account. If a company only receives a small fine for non-compliance (or is not prosecuted) then its competitor can make the argument that this is anti-competitive conduct as the non-compliant company has saved money through its non-compliance and the fine does not stand in relation to the money saved. Through this argument the fines could increase significantly over a very short timeframe placing great pressure on companies to observe the GDPR. As the money goes to the data protection authorities their ability to prosecute will grow steadily.
