No it's like demanding your new neighbors aren't forced to lend you money for your purchase - which is entirely reasonable. If you need money, get it from the bank.

"When you drop a data center into an area, energy prices will spike. Additionally, without that green energy capacity they will cause much more air pollution."
It typically takes 11-12 years for a nuclear plant to get built including planning and construction [1].
Is the idea that we'd build the data centers now, and finish the nuclear plants to power them 11-12 years from now?
