Sometimes even when a tool supposedly is adapted for your need then the tool isn't a good one.
If alignment was a hammer it would be one with a half-length unfinished and unvarnished handle prone to give splinters, and where the head was held on by simple friction while the head itself was made of cast iron so it was prone to shattering if you swung it hard.
Yes, if you only use it within the safety parameters you can use it to hammer in nails. This doesn't mysteriously make it a good hammer. It makes it the cheapest hammer on the market - and hammers aren't expensive. A hammer of a better length, better weight, with a polished handle, and a head that doesn't fly off is a better hammer even for the things that cheap hammer is supposedly meant for.
But there will be people who have adapted their technique to this terrible hammer and will protest when the kit replaces it with a better one because they are used to the tools they are used to.
