The constraining factor for blocks is the max-block weight. So miners are 
already optimizing for the right thing (creating a block that gives the most 
immediate reward). If miners want to start a cartel-like behavior of charging 
more for more value-transfer it would be incredibly harmful and even likely 
promote centralization (the cartel would likely not look kindly on any miner 
who doesn't follow their rules, and perhaps start orphaning their blocks).

Now I guess in theory you could add consensus rules that apply restrictions on 
the amount of "value transfer" in a block, such that miners are motivated to 
charge more for high-value transactions. However there's going to be almost 0 
appetite from anyone to want to do anything like this, and the amount of 
unintended and harmful side effects would be profound.  (Personally, I'd lose 
any interest in bitcoin if such a change was ever instated)
