I think what parent is trying to say that at certain point over-regulation is not helpful and actually detrimental not just to the business, but the ecosystem as a whole. For a smaller business, onerous regulation could mean closing the doors. For a big business, the burden is also there, but it can more easily withstand it due to its size ( and it typically has some resources to throw at a given issue ).
I agree that there are some 'minimal functioning society' laws like the ones you listed, but I am not certain Canada law example in previous posts or GDPR falls in the same category.
As usual, the question is that of where the line is. And that should be determined by societies at large.
