You're rambling, again for your purpose. The stereotype of LSI is policeman or guard, then Stalin: readiness is their way of life, probably the most ready of all. Busted.
I'd like to know what you'd type my brother as. He has pretty much all of the typical qualifiers of a Ti IJ type, but he is certainly not characterized by "readiness". He has an overwhelming tendency to turn things into obsessions that would be trivialties to most others. This is what keeps him continually occupied with jobs in the way I describe an ISTj above. It's what I've come to expect in ISTjs.
