"does this enables us to physically remove the SAI system from our cars, including the OBDII ones,"
No! All it does is fool/mis-represent what the O2 sensors 'see' when the
SAI air pump turns 'on', i.e. It basically indicates that an adequate amount
of air is reaching the O2 sensors during a cold start-up.

Why does that mean we can't remove the SAI pump and system from our cars? What am I not understanding here?

Please put me down for 1 ea. assembled and 1 ea. kit. TIA! You da man! 
p.s.: Still have my Heathkit strobe light and CO meter (analog...nowhere near accurate enough for today's cars.) Built many kits when I was a teenager.

Yes, you could remove just the pump, but why? When you remove system
components, it no longer looks stock, i.e. A possible future sale or an
overly committed emissions inspector/tester.
