They've implemented corruption on cash. I don't remember the exact percentage (one of these other netters who are better than me can surely tell you), but beyond 2B, you lose a small percentage of your cash each turn. If you're at 2.2B and running turns, it's probably not really a significant amount, but if you're sitting at 20B in cash, you're throwing away a significant amount of cash per turn.
Theo-casher isn't bad, and is a faster startup than rep-casher due to the population bonus, but the additional food and the tech penalty for being a theo eventually catches up to you. If you're starting up now and want to run cashers, I'd probably do theos, but if you have a full set, I'd still go republics.
Not sure where you saw that theos don't have the -20% military costs. That's still true. It's still in there.
Food also suffers from corruption/decay as well, which for food is pretty much true no matter how much or how little you have. They have implemented bonuses though, and one of those is decay, and that one's possible to get to -100%, eliminating any and all decay. I think some people are getting near the 100% point for that bonus about now (I apparently have missed some bonus opportunities, because I'm only at 80% on the ones I'm doing decay on).
Of course, as you said, ther'es also the desire to protect your stock of cash or food from landgrabs.
