I prefer to use the excuse that I have a lot of hobbies and interests and these cause the need to fill cupboards with things such as:
Fabric, wool, craft books, family history books, interior design books and related goods, a piano (and books on how to play a piano!!!), painting materials for upcycling old pieces of furniture (of which I have many in the garage) .....are you getting the picture?
As you can imagine, the lockdown is giving me the opportunity to catch up with lots of hobbies. The main issue now is, I have so much choice and time, I keep going from one thing to another in a sort of frenzy (whereas normally I would do couple hours or so a day on any one project).
I’m just so glad I never got rid of any of my stuff. I don’t need to go out other than for food and I don’t even need to buy anything online. I’m right behind hoarders now! Keep hoarding! Lol
