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.
