I’m not a minimalist by any means but I have been trying to create space and have less excess in our home.
One of the things I have done is to try to use up cleaning products/toiletries etc before buying more. However I’m now down to just one conditioner (for example) in use and one spare and I’ve started feeling a bit panicky about it. Mostly it’s just that I like knowing that any member of my household can tell me they’ve run out of something and I can hand them a replacement and still have another in stock. I feel a bit like I’ve failed in my organisation if we run out of anything 
But then also I have these thoughts like what if brexit/Russia/covid/other means there are supply issues? What if the cost of things goes up and we’re struggling for money and can’t afford to buy these things? I’d regret not having a decent backstock then. These thoughts have taken me by surprise as I’ve previously been a bit laissez faire about such things.
So I suppose my question to minimalist types out there is if I just ignore these thoughts will I get used to having less spare stuff? Or is there a way of marrying the two? One in use and one spare was what I was aiming for but now that I’m there on a few things it feels a bit close to the line!
