I find the idea of legislating how businesses operate based on the idea that people aren't expected to have personal responsibility highly distasteful.
I think the only country in the world where the general citizen have enough self control to manage this sort of stuff is Switzerland.
It might be distasteful to you but it is how people operate in real life and it would be sad if legislators ignored the real world in favour of how they wished the world to be.
I'm not following. You get your regular paychecks while you're on vacation. It's only once you've exceeded your allotted vacation days and go on leave without pay that you don't get paid. This is how things work here in the US too.
I don't think we have requirements about how exactly companies should fund this paid vacation in advance like France does (maybe we should?), but we do very much get paid while on vacation.
You do get paychecks issued regularly every two weeks (or whatever), it's just that the amount per paycheck is variable based on hours worked over the preceding 2 week period. This is common for much more than just Uber drivers (e.g. retail workers), and it still works out. The paid vacation amount is the average amount that employee earns.
That might create a pressure from employers where employees are expected to stay in their seats the whole year. The key is that employees are required to take the time off. That requirement means it's never possible to question it.
That's probably part of the equation too, i.e. that a majority of workers want a full time employment with a schedule so that they can take a few weeks off.
