There are many people who get smicha early in life and go on to do totally different things, don’t really chazer and if they do not sufficiently, and 5-10 years down the road dont really know things. There are many people who dont know more than the average yid even a year after smicha. There are also different types of smicha and yeshivas have vastly different standards. To make a sweeping claim to call every person with some sort of smicha Rabbi for the rest of his life because “why not it doesn’t hurt anyone” is not correct- as it truly can change the dynamic in a relationship and in the office.
