G. A. S. I need help, persuade me to NOT buy!

Hi everyone, I'm an amateur photographer, making photos while traveling and with my families and friends, some personal artsy project from time to time but nothing serious, and absolutely no paid work, it's just a (Dan expensive) hobby. I currently got a good setup : eos R5, rf 50mm 1.2, rf 70-200 f4, and my main trouve... 24-105 f4. It's been now months that I'm turning around the 24-70 f2.8, sometimes when I'm in poor inside conditions and it become to noisy (and to narrow for my 50), sometimes when I feel my pictures aren't sharp enough compared to my 50 and my 70-200, and everytime I told to myself "naaaah too expensive, and heavier, and you don't need it.." but damn I want it. I can have it for 1369€ on mpb if I trade my old R6 that I don't use anymore, I need you guys to help me decide if it's worth it or not :(

To your keyboards!

And thanks :)
