Propaganda Bureau, CIA, maybe even the CCE (although Infra isn't really that expensive for someone in the 3-5 range).
Actually, this would make the most sense for someone in the C10-C15 range.
Someone in the C3-C5 range should be raiding. Someone in that range is best off getting a bunch of soldiers and the Propaganda Bureau so they can raid inactives and steal their money.
There's no point for a whale to build this. 180 resources a day is nothing to a C40 nation.
However, $720,000 in resources a day is still fairly significant to someone with C10 and a very military heavy build. That's a bit too big to be an effective raider though and you've also lost the new player bonus. If you're very military-heavy then you probably don't have enough commerce, meaning that you're basically relying on sales of manufactured and raw resources to pay your bills. A built up C10 player (not a pirate) will probably have 1500-2k infra per city so they have 5-6 project slots. So you probably have PB, CIA, and probably missiles (maybe CCE or nukes if you've got a really good alliance that helped you out but most C10 players don't have the nukes). That leaves an empty slot or two depending on your war wins and something like a free $720k in resources a day might actually be useful.
