1) bigger blocks don't create transactions in and of itself. Larger blockchain probably prevents further adoption or at least slows it. Most txs you'll get will be spam which goes away the very second you charge fees. (lol)

about 2) complete bogus. Fees rise and huge backlogs won't happen even with smaller blocks because fees will drive junk txs off chain. So you got a huge whole in your argumentation there. The doom and gloom backlog-story is a lie. Won't happen. No evidence that supports this idea.

4) No, idiotic idea of exponential fee rise. Do you think btc is the only way to do txs in this universe? No it isn't. Fees will be found in supply/demand  freemarket-fashion (this mechanism never fails and no other mechanism is more efficient, free market, ya know bro? Instead of central planning, got it?)  and txs will cost exactly what people are willing to pay to use bitcoin instead of a substitute. So exponentially rising fees sounds like something right out of Hearns' ass. Again: no evidence to support this idea, niet, nada, poof, zero

all made up crap ...

use da brain, folks, use it!
