I think that what you say points to the big difference between what you can do at home versus what a company has to do to comply with laws and regulations like OSHA, risk management etc. If your struck craftsman wrench fails and a piece flies off causing some injury at home - you are not cited for using a non-compliant tool or improper use of a tool resulting in a change in your OSHA incidence rate. In industry - the cost of that risk is real - and regular and pervasive non-compliance can result in big fines and/or felony charges. Even modest contractors - especially working as subs for larger firms - need to have compliance plans for the health and safety of their employees, the public and everone associated with their work. We carry insurance and post bonds to deal with contingencies.

I was interested in buying some until I saw the prices.

We’ve been using these on the bridge we’re currently building. There are lots of heavy structural steel connections and not always room for the impact gun or a 4 foot torque wrench.
