I also believe that everyone should write the way they want. Others may like it, others may not like it. It's a matter of taste.
Still, I think I should point out something:
"...interior monologue is so powerful and easy to write
Although the writer adds 'though not easy to write well', I think that's a big mistake. Some people may find introspection easier to write, some people may find it more difficult. I, for example, have been writing dialogue scenes since I was 10 years old. On the other hand, it took me half a year of writing fanfiction to be able to write introspection. (Not 'good' introspection. Introspection in general.)
