The problem at that point is that you have the government (if that's what you meant by organization) competing with the private market for the talent required to do so. It's hard for the government to win that battle, and bad for the market if they do. And they wouldn't get the benefit of all the higher-level services these cloud providers have developed. It's not just about the infrastructure. And, ignoring the money for a moment - it's hard to see how it benefits society to have so many different organizations (including businesses) essentially duplicating the effort to build the same thing. Much more efficient to let a few larger companies do it who can spread out the development and maintenance effort more. There's room for lots of smaller companies to compete in the gaps that aren't well served by the large cloud providers at that moment.
