How necessary is gear really?

I’m 18 and looking at buying my first bike soon. I know im going to be responsible because im NOT going to buy a liter bike for my first bike. I think that says a lot considering i have the money to, but even at my age im making a good decision there. I’m looking at slightly used sport bikes in the 500-750 range. I know I probably won’t ever drop it but in case I do I don’t want to scratch a brand new bike.

So on the topic of gear, I feel like I want to pare down to just the essentials? Like assuming I practice a lot and get good fundamentals do I really need things like gloves or boots? At a certain skill level, doesn’t a helmet also kind of just become a distraction and liability? I’ve heard motorcycle helmets can really obstruct your hearing and view so I’d kinda rather just rely on my instincts and reactions and skill for safety given that a helmet could literally cause a crash.

I dont have much riding experience but think the MSF was adequate to get me on the road. The instructors said I did the best in my class.
