I know many of those, like the original surron, but they look like motorcycles and scooters, not bicycles. It's not impossible to make normal ebike-looking components go at that speed, but it will severely limit their lifespan or outright destroy them and you're still going to need an expensive large battery to make it work, so I'd be surprised.
There's the Bafang Ultra motor that can be hacked to do that (using a laptop and a special cable and shady exes from forums) but last I checked it will overheat and destroy itself without physically opening it and tweaking the thermals if you push it to those numbers. It's not easy to make a motor that can go at that speed and put out that much power and still fit in a normal bike frame.
It's already legislated to be illegal. The fact that it doesn't look like a bike means it's easy for the law to be enforced - if it doesn't have plates and looks like a bike and certainly if it's going fast that's easy enforcement. All that's missing is the pressure to get useless cops to do their jobs, but that's a solvable problem.

It'd be pretty easy to stop abuse just by limiting dry weight to, say, 30kg.

Well what more can you do? The law enables enforcement, the enforcement is easy, what else is there to do?
