No, that argument misses the point. Cryptographic hashes enable you to trust, that I only have to review the changes since the last trusted commit. That is more important for the developers and maintainers of the software and less for the users.
In order to work for the users, a thing first has to work for its makers.
There are a lot of tools where the lines blur between “for the users” and “for the development team” because the users benefit from some things that make the developers’ lives easier.
