Every single large scale retailer I am aware of, that has attempted to offer an ability to buy at least some segment of its goods via a crypto coin, directly… has abandoned this attempt after a few years.

You just assert this problem is solved by hiring ‘competent engineers’, yet no one has actually figured out how to do this, beyond basically black/gray markets, and hyper niche privacy oriented digital services.

Again, the managers, the CEOs of this business… would still need some way of objectively assessing what is and is not ‘competent engineering’.

I… assume you are not familiar with modern software related hiring processes, where it has been a running joke for over a decade that HR has literally no comprehension of what they ask for in job postings, and thus has no real way to evaluate candidates by competency, they often cannot even come close to even describing the actual nature of the job.
