What is sad is that is doesn't have to be that way. But you describe is not an intrisic characteristic of a TUI, but of using keyboard instead of a mouse. You can write a webapp that performs in the same way (modulo the resources needed of course), but it takes extra time and once it works with a mouse there little reasons to put more work for keyboard user (it is not a selling point in most cases).

The main advantage of a TUI is that it forces to write the UI in a certain way, so you get the result automatically.
