Very well put.

You can have your cake and eat it (or have both control and caps-lock
in convenient places) - if you get an intelligently designed (usually
mechanical) keyboard (thinking of the Kinesis with thumb keys). RSI is
a serious thing, particular with us Emacs folks, and often typing is
our livelihood.

P.S. Actually, another alternative to swapping capslock and control:
running a modified XF86 that lets you use the space key as a control
key "when it is pressed with another key":
