Yes.
Your lens, your money. You do you.
I just happen to prefer getting the full image quality I can get for my money instead of intentionally reducing it with filters.
I also want to get the full image quality I can from my lenses, but also protect the front element and retain as much residual value in the lens if I choose to sell it on at some later stage. Everything's a compromise; unless you only ever shoot indoors in a very clean environment, and only use lenses very occasionally, the front elements are going to get scratched and/or smeared with all sorts of contaminants. Which you then have to clean off. The cleaning process can itself then damage the front element, by introducing micro scratches, and rubbing the coatings off. Which will degrade the performance of the lens far more than any filter will in normal circumstances. I have 'retired' multiple filters from a single lens; the front elements have remained spotless and the value much higher (even accounting for the cost of said filters). I have seen lenses used without filters, that are so damaged to be practically worthless. One particular case being a Canon 24-70 f2.8 L; a lens retailing at over £2000, with a s/h price of at least £400, with a significant scratch to the front element. Worthless. The scratch was bad enough to affect IQ far more than a a similar scratch on a filter would have been. Quite why the owner didn't use a filter I have no idea.
If you really want 'ultimate IQ', then simply remove the filter for the duration f the particular shoot. No biggie. The rest of the time, it sits there doing a great job of protecting your investment.
Nikon doesn't advise people to put a protection filter because it's "better" and has no effect on image quality. They do because that 300mm f/4D most likely doesn't have a front protective glass element, which mean that if you damage the fron element of it it's a much more expensive repair, and Nikon doesn't want to pay for it while the lens is still in the warranty period.
What that note is for is to reduce the number of lenses coming back. It saves them money. That's all it does.
Accidental (or even deliberate) damage of this nature isn't covered by any Nikon warranty. That's only for defective manufacture etc. Not user error.
