> For most use cases other than video, existing wireless technologies are sufficient and will only continue to improve as things like beam shaping and micro cells become more prevalent.
Excluding today's most demanding use case doesn't get you anywhere. If you need a wired connection for that then you need a wired connection. The installed base of smartphones and tablets is still growing significantly and that's going to eat any technological improvements you can make to cellular and then some. Meanwhile people still want to be able to watch Netflix on a tablet from the back of a minivan, and to be able to make that happen at scale you're going to have to remove as much other traffic from the cellular network as possible.
> Wireless is easier to deploy and as its use grows, more spectrum will likely open up. Free markets have the benefit of deploying scarce resources where they are most in demand.
Free markets can't change the laws of physics. Allocating more spectrum is a linear increase. 20% more spectrum costs billions of dollars and only makes it 20% faster. The market solution when there is a high demand scarce resource is to shift usage to a resource that isn't as scarce for any use case where the alternative resource is viable. There is a reason one of the first things you already do when you get to a friend's house for the first time is ask for the WiFi password, and it's not because there is no cellular coverage.
> The biggest advantage of a wired home broadband connection over a wireless one that I see is the ability to stream video.
The advantage is that it allows you to transfer more bits cheaply. Today's most prevalent use case for that is streaming video, sure. It's hardly the only one. Anything that requires uploading or downloading large amounts of data is a bad fit for cellular. And we can't predict what interesting applications will become commonplace once the typical connection is 1Gbps.
> A wired connection has a lot of disadvantages: it's useless outside the home and the infrastructure is significantly more expensive.
The infrastructure is significantly more expensive, once. The cost to maintain fiber is not materially different than the cost to maintain copper. And it's not useless outside the home when everybody else has one too. If you're at home you have WiFi. At work? WiFi. Friend's house? Coffee house? Hotel? WiFi. About the only fixed places there is no WiFi are the places there is also no cellular, like the middle of the woods.
Using cellular when you're in a building with WiFi doesn't make sense. Using cellular when you're on the move does -- and that's the use case we should be preserving the scarce wireless spectrum for, by using wired connections everywhere else.
> The cost to maintain fiber is not materially different than the cost to maintain copper.
You're right; and costs to maintain copper run about 5-10% of initial costs PER YEAR. Physical networks with lots of endpoints are very expensive to maintain.

We already have physical networks. Maintaining them is a fixed cost.[1] You can't eliminate it because you can't reasonably expect to replace the entirety of Cable TV and U-verse with cellular, so the money might as well be going to maintain fiber rather than copper.
$300-500 billion is a lot to install a national fiber network because "we might as well". If they're going to cost the same to operate, what do we get in exchange for this $500 billion investment? The ability to watch Netflix videos at a higher quality? A slightly lower cable bill? (since the cost to maintain won't be significantly lower, the bill won't be either)
I'm not trying to be sarcastic here -- this is how the government thinks about things. We have an existing infrastructure that is less than optimal, but it still functions and is in no danger of imminent collapse. Contrast with our healthcare system which barely functions and is on the verge of effective collapse. Or our public schools and police departments, which have collapsed in a number of cities.
In short, it's hard to drum up political support for large infrastructure projects even if you can show the need. There has to be a demonstrable catastrophic impact if we don't do the project, which just isn't the case with broadband.
