I think I see your point of view. You see demand for on-chain transactions
as a single number that grows with adoption. Once the transaction creation
rate grows close to the capacity, transactions will become unreliable, and
you consider this a bad thing.

And if you see Bitcoin as a payment system where guaranteed time to
confirmation is a feature, I fully agree. But I think that is an
unrealistic dream. It only seems reliable because of lack of use. It costs
1.5 BTC per day to create enough transactions to fill the block chain at
the minimum relay fee, and a small multiple of that at actual fee levels.
Assuming that rate remains similar with an increased block size, that
remains cheap.

If you want transactions to be cheap, it will also be cheap to make them
unreliable.
