yeah the 2GB part was a bit too much. Especially for Mavericks requirements (I was not aware).
My point is, with an SSD, you can swap, it won't be slow as the good old HDD days. On my workstation with 8GB of RAM and a 512 SSD (MBPr), I often have 8 or more GB swapped, it's not noticeable at all.
The only downside is that yeah, the VM file size will reduce your actual available disk space until you clean it up (reboot).
You completely misunderstand memory. 4GB is the bare minimum for Mavericks, any less and even on an SSD you're delving into swap hell. 8GB is really skimpy to have just as an upgrade option, I'm constantly hitting my limits on 16GB (though admittedly my workload isn't typical).
