Well, the topic is really whether or not the EU's regulations are effective at producing desired outcomes. The comment you're responding to is making a strong argument that it isn't. I tend to agree.
There's a certain hubris to applying rules and regulations to a system that you fundamentally don't understand.
For those of us outside the US, it's not hard to understand how regulations work. The US acts as a protectionist country, it sets strict rules and pressures other governments to follow them. But at the same time, it promotes free markets, globalisation, and neoliberal values to everyone else.
The moment the EU shows even a small sign of protectionism, the US complains. It's a double standard.
