According to Steam..

Steam is a great game manager plus why do you need more then one account it basicly does everything and yes im a 64 bit os user built this rig all by myself

Also steam is the biggest game selling companies or valve persay going right now almost 75 % of games are from steam now which i find really amazing cause they came out of nowhere

plus lately steam has been giving out free games to it's members how can you beat that it encourages you to play more on there platforms

It's great, it keeps "all" games up to date, which is extremely important, without it, the "majority" of gamers would be playing games that are not updated. Also, just as important, Steam tracks the games, if you have any problems at all, due to a corrupt game file (which happens more often than people realize) it verifies it and reacquires the file(s).
There are many more benefits, but those two, plus the Friends, makes it unbeatable, far superior to anything out there. Actually Steam is pretty unique, there's nothing at all out there as good, and honest.
You can join a friend in a game instantly, track everyone, there's simply no substitute. Also privacy and security are virtually perfect.

Not everybody uses steam though. I myself hate it. I can't stand running games through such a shitty engine. The only good thing about it is that the game are downloadable, but then again, a lot of sites offer new games for downloads, or as many people here probably does (though they problably won't admit it, i'm one of those people) uses warez-sites for everything :)

Being a thief is a good reason not to like it, sure. Not saying you're a thief.. But there's far more to Steam than the ability to download games, which you would know if you used it.

No further comment on the subject.

I used it for many years, and I know exactly how it works.
If being a thief is what it costs me to avoid something like steam, then it's totally worth it :)
