Snip.
You're only considering the economy side. The big thing about frps is that it basically negates one of the big weaknesses of blobbing, which is the fact that once the blob retreats, the blobber really doesn't have a lot of field presence, if at all. With an frp, one can cut off a lot of time spent retreating and moving troops, and also provides a huge safety net since retreating practically isn't punished at all if you can be back on the field in 15-20 seconds. You even say yourself that you're a big fan of frps because having an frp close to the middle and secure is a major tactical focus. It enables people to just throw infantry at the enemy and takes out a lot of tactical depth because, again, retreating is a no-brainer when you have an frp. Taking out frps would make punishing blobs much easier and would add a lot more reason to play with a little thought. You say that blobbers will just take it in stride, and come back 1-2 minutes later. That's
huuuuuge and may be one of the effective changes to punish blobs that
you yourself stated. And really, you make keeping frps safe sound a lot harder than it really is, especially considering we're talking about okw (flakhq) and brits (sim city).
