I don't think #5 is true, but #6 definitely IS true. I've been at this hobby for 45 years + (since I was about 16 and started building). I have nowehere near the total number of media you do if I added LP's and CD's and SACD's and DVD's together. I'd certainly give you permission to give vinyl a pass.
I'd also suggest that, if you wanted to give it a try either ask local audiogoners for an audition of their systems, or buy a used $2K turntable and a used $1K preamp and have a listen to a dozen albums new and used. You can then sell your media, TT and preamp here for at least 70% of what you paid for them so your total investment in seeing what it's all about would be less than a grand.
It would seem that you love music, so either way you won't lose.
