Nobody said anything about security applications, lol. It's a proof of concept and you're getting all worked up over complete hypotheticals. Where did you even get the idea that it would have collisions within thousands?
In security applications you need to account for actors with a marked interest in causing a collision but in an inventory scenario you simply generate IDs randomly until you get one that's not a duplicate. There's no problem using a hash algorithm with collisions if the probability is small enough. There are tons of scientific labs using MD5, btw.
