Nonsense. If the free energy of formation of the amino acid is favorable, and there exists a reasonable reaction mechanism, it will form. It's not a technicality. Glycine can be formed from a mixture of N2, water and CO under electric discharge conditions. I did a Scifinder search using the search string 'electric discharge formation amino acids' and got 73 references. Here's one.

Abstract: A model primitive gas contg. a mixt. of N2, CO, and water vapor over a water pool (300 mL, .apprx.37°) was subjected to elec. discharges. The discharge vessel (7 L in vol.) was equipped with a CO2 absorber (the CO2 being formed during the discharge), thus simulating possible absorption of CO2 in the primitive ocean. The vessel also has a cold trap (.apprx.-15°), which protects the primary products against the further decompn. in the discharge phase by enabling these products to adhere to the trap. Since the partial pressures of CO and N2 decreased at rates of 1.5-1.7 cm Hg day-1 and 0.1-0.2 cm/Hg day-1, resp., the gases were added at regular intervals. The soln. was analyzed at regular intervals for HCN, HCHO and urea, and max. concns. of about 50, 2, and 140 mM were obsd. The discharge phase was continued for 6 mo. In the soln., glycine (5.6% yield based on the carbon), glycylglycine (0.64%), orotic acid (0.004%) and small amts. of the other amino acids were found.
