Yeah, meds are not the solution to all problems. Some meds can at some times be useful for some people, but it is not appropriate to just blanket the population with benzodiazapines and consider the population to be mentally healthier. All sort of other stuff like improving social connection, reducing working hours, building skills, and so on can do a lot more to reduce anxiety and depression, but where is the funding for a local community garden or woodworking class?
My understanding is you make fewer but more replicable mistakes. If you use a wire you have to trace it, keep the length consistent for timing reasons, use very consistent soldering technique, and ultimately you have a hard time tracing issues. With a homemade PCB you generally do get what you ask for in terms of circuitry. Traces are the right length, right thickness, right spacing, and if not then the whole board is similarly impacted, so it is obviously broken or not broken. If you mess up your design then you have a problem, but if you did the process right and you have a valid design then it works.
That all said, homemade PCB is a large time sink and modern PCB manufacture is so cheap and fast it doesn’t make sense to do at home for the most part. You can literally get a complex board faster by ordering it from halfway around the world and having it posted than making it yourself. I would say it is a good learning exercise, not a good manufacturing or prototyping practice.
