This seems a bit unfair, as I don’t ask the plumber likely because of trade skills being centrally licensed and regulated. Presumably if they are licensed to do the job someone else has already done the vetting - which makes sense especially for consumer-focused skills where the consumer might not be able to perform an adequate vetting.
I understand the core idea of your comment, regarding the utility of whiteboard interviews to assess skill. Irrespective, vetting is a part of many skilled jobs. The difference in the analogy and software being whether a centralised institution (Licensing body) or each company does that vetting.
