You know how much junk people buy? Yeah all of that useless crap will be cut out.

Well yes because LN is able to. That Doesn’t affect normal/other transactions/purchases. Again things priced in fiat will trend down in terms of sats until a certain point.

Well some. River is putting out average transactions of 47$. So you can convert that to sats and extrapolate trends from it. Institutions will either use onchain or liquid for fat sat transactions. So most of those will be off LN. I’m sure we will get an average size much larger than a median size. I can’t imagine what large corporations would be using LN for other than to sell and pay employees with.
