Learning to write music is not the same as learning to use a DAW. How do you know what to compose? Because you're a musician. Beethoven didn't have FL Studio sitting next to him, he had a piano with him and wrote down the things he had in his head. Your MIND is where the music comes from, not the workstation.
You can learn music first and use some inferior simpler tools to make good music (unless you're going to disagree and say the mario theme song is crap, it was done on an NES sound chip. No fancy schmancy mixing and mastering.). You can not, however, learn to use a DAW and expect to make good music without knowing what works musically and what doesn't.
If you're going to be an artist, you need to be able to create art. You can teach a monkey to move volume knobs. If you taught a guy to use a hammer and saw he doesn't magically know what goes into making a solid, sturdy ladder.
Your music would not be nearly as good even though it's mixed to 0Db and EQ'd properly.
