Presumably if the goal is only to learn how to use it, you could read the man page instead, which by certification requirements must be documented and complete or it is a bug that should be filed and fixed.
usermod as non-root user

_many_ *nix tools can be used by both privileged and non-privileged users. the non-privileged users can do the read functionality of the command, but write commands will fail.

It's easier to ban dangerous products than ignorant people

Ban the tool when the tool itself is harmless, rather than the subset of its actions which are the real evil.
It's always easier (and more politically "correct") to ban dangerous products/tools rather than ignorant and/or unintelligent people. Notice that I don't mention evil/malicious people, as we (supposedly) have a law enforcement and criminal justice infrastructure to deal with them.
While there's some cynicism in my comment, I generally agree with you—There's a lot of regulatory compliance (e.g., the OSHA labels) forced upon consumer products—some might argue too much—because the consumer public simply has too much to think about at any given moment to fully understand the consequences of (mis-)using things. Like a simple usermod(8) shell command.

Running rpm -i as a normal user checks the dependencies and then either bails out or fails because it cannot lock the database. So when installing an rpm, you can download it, test for deps, download them, test, ..., and then do sudo rpm -i ... when ready.
Removing this rpm functionality would be a much bigger PITA.
