Why don't we use the RLR in all these measurements instead of SWR?

Tradition!

Isn't
that what we are really after?

As long as you know what you're after, and get close to it, it doesn't
really matter.


A very good question. One possible answer is that RL is normally quoted
in dB, and VSWR linear scales are perhaps easier to envisage.

eg 3:1 ~6dB RL
2:1 ~9.5dB RL
1.5:1 ~14dB RL
1.1:1 ~26dB RL

Isn't there somehow something sort-of unnatural about trying to aim for
an infinite value?

As well as create something of a challenge for easy to read markings
on an analog meter.
