There is not much point is losing sleep about how words come to be used and no "we" can convince to go back, so we
literally* have to accept that and in arguments where precision matters acknowledge those different uses.
That said, I see no problem with the use of simulate and simulation as I did in my post. Just like I think a style of D&D can be "simulationist" (leaning towards simulating an understanding of a fantastic reality) without actually needing to be a simulation of anything actual or anything in total.
*The literal final nail in that coffin for me, and by "literal" I, of course, mean figurative.
