What is the point of having a proxy server for an organization?

Question

proxy

Somehow I got used to it (well, as I used to, I just always used it) to do all the settings with Internet access for users on the gateway + politicians. The "new" organization has a traffic inspector and I don't see the point in it. Besides, it somehow works indistinctly. Since billing is not needed at all, I think to replace it with something. More precisely, I think to remove the proxy altogether.
Hence the question: why do we need a proxy server? Not in the sense of what he does, but in the sense of what is the need for him?
udp. the channel is really narrow, adsl for ~15 users, some of them constantly on rdp

Answer 1

Proxy settings are usually much more flexible than those of a gateway.
Proxies can be integrated with the domain, and give access to accounts, not IP addresses.
You can more flexibly configure access to sites by ip, by url, by access time.
Detailed logs and, besides, squid is a bunch of analyzers of these logs with pictures and graphs.

Answer 2

for example, slaughter vkontaktik
or one has more equal rights than the other
