Denial seems to be all that the ID perps ever had, and the only thing that creationists like Tour and MarkE can continue with,

Hi Ron, speaking of denial, Tour and OoL, here's a real example of denial, in this case denial of the OoL chirality problem: https:// www.youtube.com/shorts/ArnQyn5tdT4

 I think that these guys just do not understand that lifeforms need enzymes to exist, and it was the first enzymes that set the chirality of the molecules used.  Why doesn't life use all D forms of every molecule?   why use L forms of amino acids and D forms for sugars?  Anyone can look to see that the existing enzymes use the L form of amino acids, so what is the mystery?  All the enzymes that use or produce amino acids would be selected to use L forms.  The exception are the enzymes that convert D forms to L forms.  The two chiral forms will spontaneously change in solution, so life has evolved enzymes that make the D forms into L forms that can be used by the existing enzymes.
 This denial will never support your Biblical beliefs.  Nothing about chirality is in the Bible, only things that make the chirality issue something that does not support Biblical creationism.  It doesn't matter if some god set the chirality because it was not the god described by the Bible.

I've asked LD this same question. I'd be interested in your comments in the my logic and understanding of the issue, as follows.
Life's molecules are now strictly homochiral (e.g. proteins composed of only L-amino acids), therefore either they developed this way from the beginning, or were purified by a later process.
If the former, this implies either an enantiomerically pure source of monomers, or a prebiotic polymerisation process that selected only one form. You suggest "specific catalysts [which] produce chirally specific reactions", but what reactions exactly, in what prebiotically plausible situation, and with what necessary amounts of material and time?
If the latter, this would involve the complete substitution of L for R units and/or removal of R units. But this would change the structure of say a protein and erase its evolved function. This alone rules out this option.
