That's effectively making the blocksize limit completely uncapped and only
preventing spikes, and even in the case of spikes it doesn't differentiate
between 'real' traffic and low value spam attacks. It suffers from the same
fundamental problems as bitcoin unlimited: There are in the end no
transaction fees, and inevitably some miners will want to impose some cap
on block size for practical purposes, resulting in a fork.
Difficulty adjustment works because there's a clear goal of having a
certain rate of making new blocks. Without a target to attempt automatic
adjustment makes no sense.
