literally the whole point of randomly generating UUIDs is that you don't need to check for collision. that's what the "U"s are for. that is the abstraction that is supposedly being provided. "using <insert Amazon AWS Certification Test Answer #7>" is not in any way a "scalable solution" for that with no other context. nor is just throwing out <random Martin Fowler concept #27>. the whole point is that it is a global (well, per name, "universal") abstraction that can, in practice, have holes that make it so you can't use it "universal"-ly.
I totally appreciate what you are complaining about. It's always been part of the documentation for a UUID. Having had Martin Fowler as a colleague and meeting with him weekly for a bit, I'd expect him to nod along with what I've written. It's standard knowledge and part of the technical corpus. As is actually distributed unique ID generation which is also not hard.
