It is possible to use loctite to help retain a fixed rear sprocket, if no serious reverse torque is applied, but that somewhat defeats the purpose. The key word in the post was reliably, along with an explanation of the principle involved. So if one wants an unreliable, cheap alternative one is free to do so, but I will never advise it.
BTW- it isn't a case of Murphy's Law but if one relies on loctite to hold a fixed sprocket, it is most likely to fail at the worst possible moment, when you're counting on the reverse torque to stop or control the bicycle. Even if you have a brake, the time and distance lost can become critical.
IMO- only someone who's ignorant or foolish would set up a fixed wheel bike without a track style hub designed for it. Feel free to dis-agree it's only an opinion.
Before flying off the handle, maybe you ought to read what was quoted. Particularly this part
If you don't use a proper track hub with a lockring, you really should have two hand brakes. If not, a front brake failure followed by a sudden extra effort at "resisting" could break the sprocket loose at the worst possible time, and you'd be toast!
Personally, I'd not ride any fixed gear without 2 hand brakes...even one with a track hub and lockring.
You also said, flat out, that it couldn't be done. Sheldon Brown disagrees with you. I was pointing that out to you.
