"Best practices" are just a summary of what someone (or a group of someones) thinks is something that is broadly applicable, allowing you to skip much of the research required to figure out what options there are even available.

Of course, dogmatic adherence to any principle is a problem (including this one). Tools can be misused, but that doesn't really affect how useful they can be; though I think better tools are generally the kind that people will naturally use correctly, that's not a requirement.
