@OP - i can understand quitting/taking a break.
What i can't understand is selling off your ships. FC decommision, yeah, because of that damn stupid offline upkeep thing. But ships don't cost anything when you are not playing.
If you return in the future, you're going to be missing stuff you might want back.
I sold off most of my ships a few weeks ago (close to 20, mostly G4/G5'd) but not due to quitting, but as a "last hurrah" in a way, sort of to break my set ways in how I play the game which became very dull (Corvette for CZs, Cutter for cargo/CGs, Anaconda for mining, you get the idea). I thought, short of resetting my save game this might re-kindle my interest in the game; I kept my FC and the 4 Imperial ships to see how that'd go.
I spent 95% of my time in my Courier, focusing on EDO gameplay (settlements, some mild plant scanning). That became boring after a few days, so I started re-building my fleet, with less effort put into engineering them (beyond G2/3 as I don't have the mats) - simply because the threat of hostile players is almost non-existent since Odyssey released. I enjoyed that, but because I'm swimming in credits and to a lesser extent in mats, it was a matter of a couple of hours staring at outfitting screens.
Exploration Krait Phantom - what put me off wasn't only the gameplay involved in plant scanning, and known issues around planet tech (I don't care too much about repetition but it's the fact the LoD doesn't settle especially when you fly at medium to higher speeds). The lighting issues with the Krait's cockpit warning lights were the final nail in the coffin.
Mining T10 - thought since I can't visit settlements without severe performance issues I should try good old Horizons gameplay again, so built a laser miner T10. What put me off here is that the lighting appears to be affected when I fire the mining lasers (i.e. everything around me goes darker, significantly so). That put me off further.
Combat Krait Mk2 (incl SLF bay) - the NPC being silent bug appears to be back, and even with a midly engineered ship (although my weapons are G5'd - I kept PP gear only) I had no trouble in the local Haz RES and while it was mildly entertaining, I want to play new stuff, not keep engaging in gameplay that I already did for the past years. What was the point of buying EDO if I ignore its features.
So in a nutshell, taking even that relatively drastic step didn't really work out for me.
The next step might be a complete account wipe, and that can go in two ways - the game becomes more fun again because I start on a level playing field (I have to go through the progression curve from the start for both ship and on-foot stuff, as such I can mix and match between the two in a more balanced way) or it'll just kill any remaining 'enthusiasm' (probably the wrong word at this stage) in the face of the engineer/rank/FC credit grinds I'd be facing.
Probably
the sure fire way to go cold turkey on Elite if I wanted to, and maybe this is the angle the OP is taking albeit to a lesser extent.
Fwiw, I haven't logged in for a while now, not even to disable the services on my FC (got billions in credits so no big deal). What might bring me back into the game is a
good performance patch, but given the tumble weed situation we're in I'm not holding my breath. And there's still the lacklustre gameplay that I don't think is going to change fundamentally over the coming months so... dunno.
