I think you're overstating the importance of satellites. GPS is probably the only useful satellite for the majority of the world, and it is an unencrypted, one-way signal.
Let's split this into military, and non military use.
Non military is GPS sure, but also weather, communications and entertainment. As well as a bunch of internet, a segment that is likely to grow a lot in the near future.
So, non-militarily it's likely that average Joe makes direct use of satilite tech multiple times per day for different reasons.
For the military there's also GPS, communications and reconnaissance. All key features of any mission.
So yeah, these things are super important. Now whether this means a "space force" I'd needed or not is debatable. I'd say not, it seems to me this is a computer issue not a location issue. Attacks on these resources are likely to be cyber in nature, not physical. Physically harming satillites pollutes the area for all players. On the other hand taking control of a working satilite delivers huge gains for basically no construction or launch costs.
Again I think you're overstating their importance. Less people are using satellite TV everyday thanks to streaming. Satellite internet is such a miniscule percentage of internet use it might as well be a rounding error. I don't doubt that will change but it will always be a fraction of the market.
As far as military goes, the US armed forces are insanely overpowered. None of that has to do with satellites. There could be a solar flare that knocks out every electronic device and we would still be on top.
It is also highly unlikely the US will ever officially be at war again. Congress would get eaten alive by their constituents. The military exists purely as a show of force, and a means of siphoning away taxpayer money forever.

In order to be "on top" we have to be able to project power outside of our borders....borders which happen to be REALLY far from any credible challengers. Our overmatch comes from a well-drilled combination of prolific intelligence collections, robust communications, and precise and timely targeting (including having sufficient information to NOT target friendly forces by accident). ALL of those abilities are heavily reliant on satellites.
Accurate imagery of adversary forces staging equipment for attacks? Those pictures come from satellites. Near-instant awareness every time a ballistic missile launches? Those are detected by infrared sensors on satellites ( https://en.wikipedia.org/wiki/Space-Based_Infrared_System ). Global awareness of where friendly troops are, down to the meter? They are taking GPS-based location data for their positions and sharing it via satellites ( https://asc.army.mil/web/portfolio-item/c3t-jbc-p/ ) ( https://www.iridium.com/products/nal-research-shout-nano-per... ). Need to pass orders and tasking messages to subordinates at geographically-distant, austere locations? Yup....satcom ( https://www.globalsecurity.org/space/systems/fleet_ops.htm ) Long-range terrestrial radio, for example HF skywave, is less reliable, has a low data rate, and presents a VERY large target for any adversary competent at electronic warfare .....which is both the Russians and the Chinese).
I thought this "end of history" narrative would be dead by now. It's incredibly naive to think that major wars are a thing of the past. The trade/commerce argument against the political viability of war has been made and debunked in the past. WWI should have been the nail in that coffin but I guess the idea is too appealing to give up.
> In The Great Illusion, Angell's primary thesis was, in the words of historian James Joll, that "the economic cost of war was so great that no one could possibly hope to gain by starting a war the consequences of which would be so disastrous."[4] For that reason, a general European war was very unlikely to start, and if it did, it would not last long.
Countries have largely stopped declaring war even when they send troops to overthrow a county. It's the kind of distiction the only matters in international politics.
Well if that was throwntoday's point, it's a distinction without a difference. The Korean War particularly, despite not being officially declared as a war, came disturbingly close to going nuclear.
China has already threatened to shoot SpaceX's starlink out of the sky because it poses a NatSec risk to them by puncturing their Great Firewall.
While GPS is hugely important - no debate there -, there are quickly growing alternative uses for satellites. Also, satellites are already used a lot more in business than people realize [2]. Walmart, for example, used to own the largest fleet of satellites in order to connect their stores to HQ before communication was ubiquitous. It built it out in the 80s.
