If the BTC price keeps on increasing, fees must rise with it to keep the fees to pennies (0.001 BTC fee would be $10 at only $10,000 per BTC with 1MB blocksize).


You're going to have to admit, BU "scaling" doesn't scale up at all. Even a $20,000 price, which is a pretty modest medium term expectation, would cause untold problems. No-one seriously thinks that blocksizes big enough to give you your penny fees at those price levels is a sane direction to go in.
