But it won't. You attempt to comply with the rules, show good faith and you won't be in danger.
It's not a real risk.
So the moment some group "wants to make an example of your company", not that I have ever heard of anyone being made an example of that's remotely akin to US punitive damages awards or 999 year Texas jail sentences, you appeal to the national or EU court. The judge will be delighted to rule the regulator's (or government) actions illegal or disproportionate. It may well also trigger a judicial review.
For an alternative outcome you would require a change in representation at the EU from 27 nations, and repeal of one of the founding principles. Not as unthinkable as the US repealing the constitution, but not very far off.

How is that a bad thing to do? Pretending that the worst result couldn't happen is just delusional - it is like people who don't wear seat belts or helmets, or don't buy insurance. Just because something is unlikely doesn't mean you should ignore the risk, especially when the consequences of the unlikely even are so high.
Yes, the maximum penalty is probably pretty unlikely; on the other hand, if you GOT the maximum penalty, it might be a death sentence for your company. When the stakes are that high, you can't just ignore the risk.
