The price of Datacenter are the AI chips but the bottleneck in creation of them is power, given how much power exhaustive they are (and rightfully so) people protesting against it because its them who pays the price.

That being said, the shipping container idea is decent but the bottleneck is still power not so much cooling, so unless someone figures out a way to have an actual nuclear power reactor, there are issues.

Also oh the issue isn't that there aren't nuclear power reactors but that they aren't large enough. Some nuclear powered datacenters exist in some experimental settngs but these new Datacenters are trying to take a magnitude more and they can't wait for the production of those things and further research.
