Once I found setups that really worked for my wife and myself, I ended up shifting my buying habit to stocking up on the things we like. It was originally driven by the feared vapocalypse and regulation. Over the last year, the motivation has become more to get it while we can, as models come and go in a heartbeat in this frenzied market. I am actually buying more than I expected right now thanks to clearances. At this point, I may not need to rebuild heads for at least seven years. Every six weeks or so, I throw together a 600ml batch of of our ADV and just go on vaping. The occasional interesting premix, maybe another used Provari, that's about all I will be adding. The peace of mind is great, but I do miss chasing the new shiny stuff deals!
I admire the OP's plan to PIF or sell the equipment that isn't going to get any use. The hoarder in me hasn't quite gotten that committed just yet, so a couple dozen mods hang out in a box, waiting for action. Time to thin the herd for me too!
