With that, you're getting into the concept of "fictitious play" or simulations, where one players imagines using a strategy, the other adjusts his to exploit it, and then first reacts to that adjustment, until they come to a new equilibrium. While they establish an equilibrium, it's akin to a levelling war. Ultimately, higher rake has to lead to both players playing tighter.
To put it another way, the BTN might think "I can open wide, because the BB is folding so often", but the fact the BTN is opening wide means the BB should start defending more, and when he starts doing that it means the BTN should tighten up, which means the BB should stop defending so often... etc etc.
In the real world, players that react or adjust to changes in the game more quickly than others can gain a profitable edge.
If the rake was quietly increased, the player that noticed and adjusted his strategy the soonest would get an edge. You see this in things like tournaments, when some players don't change their strategy when antes first come in, when those antes mean the pre-flop "solution" is actually quite different to a no-ante game.
Another example would be in a specific SNG or tourney that has its rake changed by the room/site. A rake increase in a hyper-turbo (for example) might make the game unbeatable (or at least
less beatable), and the good/obsevant regs will immediately stop playing that format, but the bad regs (and fish) won't even notice. Sometimes, so many regs quit the game when the rake goes up that it then becomes profitable for the few that stay (because the reg:fish ratio is better).
