Is that an "excuse"? I mean, what even is an excuse? I think it is simply reality. Only, I still think we should all not want centralized systems capable of controlling the flow of information, money, etc. The decentralized systems we have at this point aren't bad... they just aren't as good as current centralized ones. Hell: they even compare favorably to the 90s-era centralized systems!
As it stands, rather than trying to increasingly regulate these centralized systems in the hope they eventually go away, we've been instead subsidizing (or even "bailing out" in some cases) their awkward control, giving them power beyond what anyone previously could have imagined, enabling their crazy scale, because... it's efficient and easy? That's super lame :(.
