A monitor's enclosure should be his home, to defend if he sees fit. I don't get gloves, I use them when I hand feed larger monitors, because I've taken one too many bites to trust them too much, but for handling, they just get in the way. I wouldn't really consider argus or sav claws all that bad anyway, they are child's play compared to some other monitors. If you are getting injured alot from handling, you are probably handling them too much.
What I really don't understand is what the heck people do to monitors to make them so defensive. My monitors are actually very tolerant of me, as long as I respect their boundaries, they have no problem with me changing water or doing cage maintenance, if they do, they go into a burrow or log until I leave. Sure argus will hiss, puff and posture at times, peachies too, but as long as you don't go poking them or picking them up, they go back to their business. The only very large exception is feeding responses, which all the tameness in the world won't change (tamer ones can actually be worse), it seems to be much more hunger related (and to a certain extent species related). I do have certain enclosures that precautions must be taken, because the monitors have proven to be very willing to believe, that just maybe this time, fingers are food.
And sure the monitor would die if we didn't care for it, but we made that decision, not the monitor, I don't see how that justifies demeaning it's life even more. Perhaps some people just need to be nicer to their monitors.
