It has nothing to do with bites, but a person who is capable of handling the animal with safety.....a bite is a risk we all take when handling animals, not just reptiles, when you do it for a job, then it is common knowledge that bites happen, it is unfortunate but many people who work with animals eventually get bitten for a variety of reasons.
What you do in the privacy of your own home is up to you, but to display such disregard for safety in public is just being a cowboy, an ego trip, and mostly to set up bragging rights! For the safety of those working with venomous snakes they should not be freehandling, I know for a fact that should a bite occur and an investigation is undertaken, if a person was freehandling then it is highly unlikely for them to be covered by insurance! Today it is not regarded as best practice, especially when there are other safer methods to hold venomous animals without stressing the animals while also increasing the safety to the handler.
