I don't think so. Most vehicles have virtually no braking power with the engine off. It's definitely completely forbidden in France to tow with a rope, and I'm pretty sure this applies to all or at least most of UE too. In Germany, even tow dollies are forbidden.
Towing rope is legal in Germany, but you are only allowed to tow a car to get it out of the way and to the nearest repair opportunity after it has broken down, not for general transport - for that, it needs to be completely off the ground.
If you’ve always used power assisted brakes and you’re not expecting to have to press really hard on the brakes it could easily lead you to rear end the car towing you if it stops suddenly. Also, without power assisted steering, modern cars are surprisingly difficult to control.
