Are macros necessary?

[Jamillion]

Macros are actually inefficient and it's better to not use them in every aspect of the game. Really just a tool for you to be lazy, but they cause lag and make things take longer, and if you use them on battle jobs they will cause you to miss several GCDs in the long run. You can get away with it on crafting jobs if you're geared enough, but it's always more efficient to do it by hand.

So no, not necessary, and actually better if you don't use them at all.

I think you're underestimating macros. Not saying they're essential or anything but there are a ton of useful macros you can create. Text macros to announce mechanics without voice chat, macros to disable b4b or regen, hunt macros, gearset/sorting macros, the list goes on and on.

To the OP, macros are not essential to enjoying the game but you should experiment with them to see if anything you can do would be enriched with them.
