The *...* emphasis was basically an attempt to differentiate "will eventually comeday quite likely really really seem to actually right then urgently need" from "we right now do urgently need it, we are losing adoption rate and suffering lowering exchange rates every hour or day we fail to get a higher limit into use".
Yes the apparent/seeming "need" will tend to tend upwards.
But, constantly pulling the rug out from under infrastructure development that also will tend to seem more and more "needed" in a basically fundamentally doomed attempt to turn the world's highest difficulty currency-of-final-international-settlement into a retail payment processor so people can buy penny candy using e-currency despite no longer having pennies in the snailmail world doesn't seem a productive response.
We not only have 1 megabyte per ten minutes of international final settlement transaction space, we also have, secured by that same hashing power, several other sets of blocks (namecoin, devcoin, ixcoin, i0ccoin, groupcoin, coiledcoin, and it is easy to add more) that have already established tendencies to cater to lower-value transactions (by using lower-value coins).
So if people still feel a need to spam out to the world trivially small value transactions (which to the primary chain might mean less than a few thousand dollars worth, to the first secondary chain might mean less than a few hundred dollars worth, to the second primary chain might mean less thans of dollars worth (at this early stage; later multiply all those figures by a power of ten from time to time as adoption proceeds).
So plenty of space is out there for low-value transactions, and more can be added very easily and moidularly (add another chain, add another chain, all the time each chain remaining fully and easily within the capabilities of a single home computer on a home internet connection to fully verify).

While it's true that Bitcoin adoption is outpacing hardware growth in the moment, this trend will not last. I'm in the midst of writing an essay that goes deeper. Hopefully my calculations will allow us to move forward together, rather than bicker about how necessary a size increase is.
