Australia and the UK both have a similar business environment to the Swiss model (but without the superior bandwidth) due to the way that their government-owned telephone monopolies were privatised: Telecom Australia (now called Telstra) and British Telecom (now called BT) were required to allow their newly-formed competitors to sell services over their networks (for appropriate maintenance fees, of course).
The US and German models are consequences of just yelling 'Free market!' without stopping to think about what's actually being sold in that market, and how to encourage genuine competition.
We've had the same issue in the Netherlands as the UK (telecom getting free infrastructure), and the end result is them blocking every fiber connection for years and then buying up all of the ones trying when it suited them. And the cable companies had a freebie for decades because they got most of their infra for free without the "share space" requirement (because only a major part, and not all, was funded by municipalities and it took a while to get them all in one company), and the cable companies decided not to invest in anything. And now we have the fiber-to-the-bottom where they are installing as fast as they can, but only with a governmental monopoly in place with dubious sharing agreements.
Due to "competition" and "fare ride" my soon to be (it's taken over 4 years and likely will take forever..) fiber will cost me 22 euro/month more than if I would have gotten the cable from across the road ... but the companies have "exclusive" rights since they would not have "financed" it otherwise (the quotes are all marketing bs).
Australia has the absolute worst internet

The point of a system is what it does. In America, it fosters centralization of wealth on a massive scale. That’s the point, not some unexpected side effect of the theory nobody saw coming.
Australia is still pretty messy, Telstra was privatised and pretty much stopped upgrading their network for years around the 24 mb ADSL level
Eventually we had a forward thinking prime Minister create a new company that started running fibre to homes and wholesaling it to non government businesses but they lost power and fibre to the home became fibre to the neighbourhood running the last bit over existing phone lines
Eventually it was returned to fibre to the home as upgrading existing lines to run shitty 100mb connections was actually much more expensive than just running fibre
We're only now starting to get to the point where fibre is fairly available when it could have been ten years ago
