And I do not agree that in BJT-based circuits "controlling the current is the simpler way to approach it. "

It is simpler because I can easily come up an exact current that will ensure saturation, but not a voltage. And you did the same, while denying that you did so! Your argument falls apart when you don’t even use it yourself.

Yes, you've made your opinion quite clear.
And my opinion is that you can't easily do switching circuit or bias circuit calculations using voltage control.
You've done a large amount of arm waving about that, but I see nowhere that you've actually shown how that can be done without calculating the base currents based upon the design transistors collector current.

I never have denied that there is a base current and that we can/must estimate resp. calculate its value.
To make my position clear, let me list some classical and proven steps for designing a simple gain stage:
* Specification of the required gain
* Selection of a suitable DC collector current - in conjunction with the collector resistor Rc
* Selection of a corresponding emitter resistor Re (DC stabilization).
* Calculation of signal gain (design verification): A=-gm*Rc/(1+gm*Re) with gm=Ic/Vt (Re=0 for a capacitor Ce)
* Selection of the base bias voltage divider (small resistors - as small as possible from the viewpoint of power consumption and signal input resistance)
* Of course, the base current Ib=Ic/B is taken into account (rough design rule: Current through the divider at least 10 times the estimated base ciurrent). However, in some cases (large B) you even can neglec the base current for this caculation with an acceptable error.

Finally, I have only one question to you:
At which design step is it helpful (or even neccessary) to use the current-control view? Rather, is it not the case that I only make use of voltage-control: (1) gm-determination, (2) Re-feedback effect, (3) small base resistors (stiff base voltage).?
I am really curious for your answer.
