You *can* build a decentralized technical / internet system which is actually decentralized, of course. There are lots of examples of that too. But since that isn't the kind of system capitalism naturally builds, what you probably won't do is get *funding* to create that system. And that means *completing* your decentralized system is hard and gets harder the further past 1990 we get and the more you expect your decentralized system to do.
@mcc I thought this before, the internet's key resilient design principle is diametrically opposed to capitalism's requirement for control of resource(s) and cultivation of dependency - eg in capitalism you want to own the only bridge over the river.
