I think my message might have been confusing with some of my examples. 

My base currency in my personal financial management and business accounting software  is Bitcoin denominated, not USD. The opposite of all other financial software that treat a Bitcoin as some kind of investment or asset like a stock and tracks its value in USD. 

I immediately convert all fiat I receive to BTC and store it that way except if I get some fiat cash which I carry around in small amounts to help the needy I encounter.

Whenever I can, I pay bills or make purchases in BTC directly. If I have to use fiat to buy I use a credit card and pay it off in full each month by converting sufficient BTC to make the payment. So USD is only a payment rail I use for receiving or sending value I measure and account for in bitcoin. 

For example, I recently took a cruise and covered expenses for my brothers in USD that we would split at the end. Each time I spent in USD I was mentally thinking of how much Bitcoin that was sometimes using the calculator if I couldn’t do the math in my head. At the end of the cruise, they paid me back in BTC that I had kept track of. When the credit card bill in USD is due later this month I will convert BTC to USD to pay it because I don’t have any cash balance in USD. 

I follow this pattern as much as possible. 

While prices are mostly not quoted in bitcoin, I mentally or manually convert the quoted price to bitcoin to determine relative to my bitcoin holding whether I’m comfortable making that purchase. When doing this over time every thing costs less in bitcoin to buy.

It isn’t a perfect system and most people cannot do it as it takes a lot of focused attention and change of mindset.  But I’m motivated to force myself to do it and create the tools to make it easier so others can adopt them in an easier way and not have to do so many mental gymnastics. 

 One more thought, as a business owner I’m trying to calculate and understand my costs in bitcoin and then set my prices in bitcoin as well (I have a subscription based SaaS company). Since some customers cannot or won’t pay in bitcoin I offer a USD price converted from the Bitcoin. 

This is new and I’m still working out the details but if they pay in bitcoin I expect to gradually decrease their price while if they pay in USD I expect to gradually increase their price. They get to choose which way to pay. 

 The entire point is to start trading real goods directly for Bitcoin and to get away from the USD-denominated measurement as quickly as possible.

When small communities, online communities maybe, are producing things of value that can be directly exchanged for sats.

i don't care how smoothly you can interact with the fiat system or whether you do you accounting in BTC. UoA doesn't mean your personal accounting. UoA is the measurement the great mass of us have agreed is the most saleable.

but thats cool to be able to conveniently move between currencies. low friction is better that high

but the point is to directly transact p2p.
and aa much as you can, just send the sats you think it's worth.

for this to happen large scale we need energy providers who take BTC for payment. that'll be a big thing. 

 That’s a good point. I appreciate your perspective as it is definitely a complete and fair definition of UoA
