There's 300 million plus people in the United States. Sure, we could overthrow the government, but you can't just go "my way or the highway" with policies; you'll never get support doing that. As spoonjim said, Trump wasn't elected for no reason; He was elected because 62 million plus people voted for him. And with this past election, that number went up to 74 million. And the opposition (Biden/Harris) got 81 million. For comparison, George Washington's support was almost unanimous. Sure, it's not exactly the same, but Washington had the support he did because everyone believed in a common "enemy", the British Empire. Today, depending on who you ask, the enemy is either "the Demonrats" or "the Trumpanzees".[a]

Not to mention that the United States itself wasn't formed overnight; it was the product of many compromises. There's even a whole Broadway play about it: Hamilton[b].

[a]: Yes, these are actual "names" I've read online.

[b]: Sure, it's exaggerated, but it's pretty accurate
