Because some people some times don’t WANT to know what is mutar and what is asur!
There was a movie (you should excuse the reference) 35 years ago, i.e. in 1975, called Hester Street. It was about two close friends, frum Yidden who came to America at the turn of the century, from Europe, and were struggling to make a life on the Lower East Side of NY. One was single, and the other married. The married one came alone, to work and save up the money to bring his wife. By the time he was able to do so, he had already gone “off the derech” and given up his frumkeit. When his wife arrived, she, of course, was frum, and his friend was still frum. In a very memorable scene, the wife turns to the friend and says (I don’t remember the actual names of the characters, but…) “Chaim, I don’t understand, what’s happened to Yakov?” The friend turns to her and says “Chana, you have to understand, many of our people, as they got on the boat in Europe to come here, looked up and said “Good bye L-rd, I’m going to America'”.
—Now, “kvod hatorah” fast forward one hundred years… Sadly, as many Yidden hit the Thruway, they say “Good bye L-rd, I’m going to the country…”
