Yes, but, how can I say this gently and politely, there is a big difference between "nothing bad has happened SO FAR" and "nothing bad is going to happen".
Predatorproofing is one of those things that you don't know you have a weakness til something tries to exploit it. Nothing bad having happened so far doesn't necessarily mean anything. Look at how many of the "something killed all my chickens last night" threads come from people who had chickenwire for months or years with no incident, or who have neighbors whose chickenwire was never bothered by predators... right up until the morning you come out to a pile of bloody feathers.
If a person is ok with risking losing chickens (possibly all of them) to save really quite a small amount of money, that's fine, everyone has to make their own choices about what's important... but I think it's really important to understand that just because there are people who haven't YET had problems with chickenwire does not by any stretch of the imagination mean that it is as predatorproof as stronger wire, some of which is not really any much more expensive (although needing smaller hole material added low down).
Dogs etc. REALLY DO go through chickenwire. Heck, they can rip through the cheaper lighter chainlink too. How well do you want your fence to stand up to a dog (etc) that is sorely tempted?
