I will touch on one that I have seen people mention, but really the only reason for me.
Health...
As a homebrewer and beer lover, I always had A LOT of beer floating around the house. My beer, macro beer, rare craft beer, other people's beer. Way more than anyone I know. With that, it is super easy to go grab a pour, or go grab a bottle.
I started to brew a lot in 2017, and just increased from there. 2018 and 2019 I brewed about 20 or so batches of beer each year. And, I am the only one in my house that will drink it. And, a lot of my friends are not super into beer, especially craft beer, so they didn't help very much. I ended up with a ton of beer for myself. So, I drank it...
I gained a few pounds from it for sure (I am probably +20lb in the past 4 years). And, more scarily, some early signs of alcoholism started to show up. So, at that point, I decided that I needed to slow down on it a lot. Call it a lack of self control on my part. Its too easy to just take a pour off the keezer any time you want. And it lead to other things...poor sleep, feeling like **** in the morning, poor gut health, increased inflammation, increased anxiety...not just the weight gain...
I went from 20 brews a year, to about 4 or 5. I still love it, and still 100% love beer. But for the sake of me, I had to slow down. And I can 1000% tell the difference in how I feel now vs, 6-8 months ago. Like night and day.
Will I ever stop or sell my stuff? Absolutely not. Just have to be more responsible...
