On the contrary, almost all of them have that monopoly, oftentimes to the point where they've negotiated with exclusivity arrangements with municipalities. This means that even if Google, Apple, Netflix, etc. are willing and able to to lay down their own infrastructure, they're prevented from doing so by the government. If that doesn't make ISPs deserving of Title II regulation, I don't know what does.
Other sets of wires into the home exist and are capable of delivering high-speed internet. (Most notably: legacy copper wires offering DSL.) More wires can be run, just like cable TV was. It'll be even easier now than the cable buildouts of the 60s-80s; the world is richer, awash in capital, with better tools.
Wireless also keeps getting better and is now competitive with wired for most daily internet needs – email, web, VOIP, audio streaming, light video, gaming – all except for bulk HD video. (Just like people have 'cord cut' their cable TV to rely on net entertainment, others are 'wire cutting' their fixed-line internet service, and relying solely on their wireless internet, from one of 3+ providers.) So speaking for the US, most people have 6+ options to get core internet service. That's no "ISP monopoly".
We agree that locally-franchised monopolies over certain wireline services are a problem, where they exist. (OTOH, some localities have enabled multiple cable companies and other competitive wireline services, like Google Fiber.) Those localities with bad policies should undo their mistakes, as they see neighbors and peer-localities having made much better choices. But those scattered problem communities are no reason to compel a specific national service formula on all ISPs everywhere, even where there is competition.
Isn't one of the major arguments for net neutrality that, at least in some parts of the world, the above situation is effectively what is happening today, and therefore the local ISP can effectively hold the entire community hostage?
But in the US, most people have 2 or more wired internet options and 3 or more wireless internet options. The feared abuses are almost entirely hypothetical-future-risks. Any attempts to "hold communities hostage" would create massive openings for both competitive marketing and technological countermeasures.
By all means, any local communities being "held hostage" by a single provider should remedy their situation. Locally.
In other words, almost all the evidence I've seen as an outsider suggests that much of the US does not, in fact, have a functioning competitive market for residential high speed wired Internet access, but rather a complete monopoly whose single provider will furthermore spend a fortune on legal manoeuvres to defend that position if necessary. The net neutrality movement and efforts to classify Internet access as an essential service subject to regulation seem to be the first serious moves at national level to counter some of the resulting problems.
Let ISPs try to abuse their momentary position. They're newish businesses in a rapidly-changing market and technological environment. Not one of them has the same "single provider at any cost" monopoly that phone companies had when the Title II telecom regulatory regime was designed.
Some of the companies they might try to shake down – Google, Apple, and others – have the capital to route around them with better services.
