This isn't true. I've run 10gbit over cat5e many times in 10-30m lengths. That might not be enough for end to end on your house (although it is for many peoples), but it's certainly fine between floors.
10gbit switches are becoming significantly more common. Vendors like fs.com and even Netgear offer some reasonably priced options. Mikrotik and other vendors offer better (pricier) options, but assumedly if you want 10gbit (or even 1gbit) you're an enthusiast or business anyway.
