You are wrong, yes.
You can adjust the intonation on a Ric.
As for individually adjusting the saddle height, why would you? The bridge matches the curve of the fingerboard, so it’s set once and forget.
As for the truss rods, you have to use a different technique to adjust them on vintage 4001 models to what you would do on a Fender (which has now become the defacto standard, but wasn’t in 1960). If you don’t like that then don’t buy a 4001 (which haven’t been made for 30+ years).
4003 truss rods adjust just like any other modern instrument, except you have two, so you can tweak the action across the neck too.
Ric truss rods are also user replaceable, if you ever need to and you can buy the parts from RIC.
Demanding RIC adopt the Fender way is ridiculous.
