Yes I understand. I am saying that there are literally dozens of types of machines you can build using a condenser alone (no collectors), that will just sit there, while you are offline, and produce EMC, just like a power flower. And they will do so in some cases orders of magnitude faster than power flowers will for the same cost. A single rotary macerator, a condenser, and a couple of windmills can produce 1500 EMC per second, for example (as much as over 60 Mk 3 collectors!)
In fact, even if you ban condensers, that's still not good enough. If I put a gem of eternal density in an alchemical chest, then I can pump stuff from a darkroom or a blaze rod grinder into that chest and still end up with a concentrated source of offline EMC.
So you would need to ban condensers, collectors, (alchemical chests and alchemical bags) or gems of density, transmutation tablets, probably black hole bands, and mass fabricators. And I'm probably forgetting some things, still. I strongly suggest simply banning all of EE2, if you want a "legit" finite resources survival server. (And mass fabs)
All of these things except the mass fabs can be banned using the EE config file in the root directory.
