I've worked with folks who were concerned about a program needing another ~750KiB of resident memory because the typical use case was to run tens of thousands of instances of it on a single host, and it was a big ask of the typical admin to "just add some 10s of GiB of RAM."

It also doesn't really prevent people on figuring out alts, it just shifts the effort of doing it around.
On the other hand, shifting effort around, or increasing the amount of effort required... that can be enough. After all, much of modern encryption and hashing isn't based on making it impossible to recover the original text. It's based on making it infeasible for some (large) collection of adversaries within some (large) amount of time and resources.
