I think your example just fortified his comment.

I can't make a car company. I can make a webcam on doors company.

And you might say it is about raw materials. But I can buy enough materials for one car and one webcam door. I can't put the car on the road (as much as it make sense) only because of the sheer amount of cost required to pass regulations.

So while regulation is something we want as costumers. I think we'd prefer to not have it become a obstacle in the software sector to the point it exist elsewhere.

That is why I think the GDPR is great since it applies to companies with 250+ employs.
