I do. If, say, I need to spend $20-25* on a new 128 GB SD card, I actively think of the opportunity cost of a nice .999 silver coin I could buy instead. This goes for food, entertainment, utilities, etc - everything. I put everything in terms of government issue .999 silver rounds, or the next new coin I want to purchase. With this perspective, I determine if non-coin purchases are "worth it". If I get stuck, I put it into extremes. For example, is the short term pleasure and memory of a whimsical night-out, worth buying and keeping long term a unique and rare silver coin that's not even on my wish list? It definitely depends on the specifics, but that's generally how I look at things. How about you? Am I the only one that thinks like this (it may be a bit extreme)? *Why? Because I want to future proof the things I buy with higher quality products so as not to buy them again or anytime soon - average yearly cost tends to be cheaper.
Fortunately for me, or perhaps unfortunately, I have a $50/month budget so I don't have the pain of weighing everything I purchase against what coin or silver I would buy instead. I do, however, have every cent I make budgeted towards something, to include savings, and so I do compare what we are going to purchase (food, gas, going out, etc) with what we have in savings and what we could be saving.
The only thing I think about is how many coins are going to have to come out of my bank account purchasing that SD card or for that night out. I have a rough budget for coins that, relative to my bank account and paycheck, means I can buy the SD card, go out for the evening, and still buy a decent number of coins, and that's enough for me.
Seems as though the end result might be that your financially responsible to yourself rather than the consumption debt economy.
I do that sometimes. I'll buy something that I probably didn't really need; more of wanting it and then think to my self I could have used the money to buy a coin or coin supplies.
I kinda do what you do only in reverse.... I calculate how much silver I need to liquidate to buy this or that.
