Of course decentralized architectures are not without downsides, just like any engineering trade-off. I'm not so sure it is a
strictly negative feature for a lot of people though -- they may just consider it an overall negative due to some conveniences they may have lost as part of the trade-off.
And that's okay. It's important to bear in mind the things lost by not being decentralized also, though. I think this is presently not very prominent since a lot people started using the internet for a few large centralized services so they are not very familiar with the idea. Arguably, there was a period when people flocked to the internet because of the newfound decentralization.
> I'm just putting across the counterpoint that it's not, there are circumstances where unilateral control could be (and is, by large sections of the population) seen as a good thing.
It's seen as a good thing as long as the single point of control is doing things which are (mostly) aligned with the desires of these large sections of the population. This is a tautology. History teaches us that this is not at all given, though, so it's important not to rely on it strongly.
> I mean, you can. I'm not necessarily saying it's a good thing to do, but there's no real reason a government couldn't make exactly such a rule. Whether it could be enforceable in any way is a different matter.
Well, certainly. You can declare anything at all. I was proclaiming that from a position of practicality.
