I'd really love it if the 10GbE cards would drop under $13 :) And especially the switches to become cheap.
It really feels like we've had 1GbE like forever (it was already standard on my 2004 PowerBook!!). But 10GbE is still hardly affordable.

"10GBASE-T, or IEEE 802.3an-2006, is a standard released in 2006 to provide 10 Gbit/s connections over unshielded or shielded twisted pair cables, over distances up to 100 metres (330 ft)."
I spent a few years implementing 802.3 physical layer testing. At the conferences it was clear that things were written carefully to not cover implementation, but they went so far in the necessary details that there were only a handful of reasonably performant and economical solutions.
Prepare to be very surprised, I guess? It’s pretty routinely done, eg) look at any of the MPEG standards.
I don’t know what patents, if any, cover 10GigE, but in general IEEE, which governs that standard, will accept Essential Patent Claims in a standard provided the Patent Holder will provide a Letter of Assurance indicating that they will license said patents under FRAND (fair, reasonable, and non-discriminatory) terms – which does not mean free.
At the end, I just got motherboard with few 10GbE and SPF+ on it.

And can most systems push this kind of data?
(home systems)
SSDs are an order of magnitude faster than gigabit ethernet.
Google fiber is rolling out 2Gbps internet in many locations
1 Gigabit is definitely good enough for most general use cases, but once you start moving files around regularly it becomes a huge bottleneck.
People will compare browser benchmarks over milliseconds so why not file transfers over the home network?
In general terms, cynicism about the "need" may be right. Most home users in most use cases likely won't notice much by going to 10G.
But then there is the rest of us and the other use cases.
As for systems that can push this much data. Almost anything with a M.2 SSD will easily keep up.
So for a use case, backing up your zillions of photos to at least one other point of failure on your home network. May not be the best backup plan ever, but regular home users are not IT gurus and will do this.
So yes, it's trivial to saturate a 10 Gbit/s link, assuming that the kernel and userland can keep up with the hardware.
Wifi 6E can do almost wigig/uwb speeds, near 7Gbit hypothetical.
A single modern NVMe drive does 56Gbit.
USB4 can do 40Gbit. It can connect direct computer to computer.
But indeed as others have said, even broadband connections are exceeding this speed now. USB exceeds it by a factor 40 and is on cheap laptops. Yet Ethernet remains so expensive.
