I don't get it. Some items on that list can be legitimate, non-technical objections, like 3, 5, 7, 30, 31, 33, 56, 58. Others can be legitimate, technical objections, like 1, 6, 19, 46.
Anything can be a legitimate objection. At some point you have to just try something.
That's terrible advice if the objection is of legal nature, for example, or when human safety is at stake. Also, you typically don't have unlimited resources, so "you just have to try something" isn't a good justification if there valid objections against its feasibility.
Yes, advice without context is terrible. Any objection can be a good or bad objection based on context.
Eh it worked well enough for the whole history of humanity so far
All of them can be legitimate. It's just that they almost never are.
