He seems perfectly safe surrounded by that framework, the cow will be calmer with the presence of a familiar human, I don't see why not. I also don't see why the system exists, given the cow could be driven, or trained to walk up to a lick block or down to water (the latter will be at around 4pm when they want a drink and to go to bed).

I'm sure a logical reason exists. If this is in Eastern Europe, that reason may only exist in the mind of a bureaucrat who got his job through loyalty to a political doctrine and what family he was born into, he didn't have to actually understand farming cattle.
