Of course there are some great stations to stream; there is infinite musical content online that I use to great advantage. But we're specifically talking about FM/AM broadcast and the chaff heartily outweighs the wheat in most locations.
Just because they also stream doesn't mean it's not useful to know about.
The internet was a boon exactly because I was sick and tired of all the FM stations that I had available, with their narrow and small playlists, and it allowed me to discover whole new genres and authors (including by listening to online radio). In the mean time, FM just become even worse. The first half is essentially all I have available, do you care to choose a great one? https://radioonline.com.pt/
You shouldn't assume everyone has the same access to good things you did and must be lazy and narrow-minded.
