Negative sats flow is not long term sustainable. What happens once all your sats are gone? Doesn’t matter if value of sats is going up if you have none.

From the way things work right now with satoshis being the smallest unit of the network you are correct, but this is a network that will last thousands of years. Considering that long term outlook Sats will eventually be further divided with a BIP, likely within a decade IMO. If that indeed occurs, one can manage to never run out because they'll just use an ever decreasing amount of their stack over time.
Something kinda like this
My mathmatical training is failing me here, could you explain? I'm unfamiliar with this.
In each step the reduction is a smaller unit. First one half, then one fourth, then one eighth, and so on.
Okay yeah. I envision a future code addition to the halving cycle that increases the division by another decimal. So every 4 years when the halving cuts new supply by half, the total supply is further divisible by another 10.
The answer to that math equation is zero. Doesn’t matter if you keep reducing denomination. Negative sats flows eventually leads to zero.
Eventually you would be spending such small amounts that you wouldn't be spending Sats quicker than the value of the remaining stack grows in value, effectively never running out.
