When talking about public pieces of information, being able to refer to them by their identity is useful and any hashing would be counterproductive (just wasting power), also, I'm sure any database can operate on unique, incrementing numbers more quickly than uuids. If we're talking about private information, it should be transferred in another way than the url in the first place, yes, the chance of "guessing" a hash is lower than an incrementing number, but there are other ways it could be intercepted, a screenshot, accidential copy/paste for example.
