Yes. An attacker who is prepared to spend the same amount of money as all other network players earn combined can do various attacks.

The goal of the "halve every 4 years, plus transaction fees" model is to make sure the above is never possible for an attacker.

They either need to sway more than half the miners to their evil side, or they need to exceed the total of everyone else.

How can you have more than half without more than everyone else (who by definition have less than half) combined?
