First proof: if Trump has surrendered to the Left and has no intention to oppose them, they would not rile him up with impeachment, a string of state lawsuits and vilification of all his followers.
Second proof: if it was clear to people who know more than us that Trump has thrown in the towel, smart insiders like Pompeo and Jordan and Gaetz would not be so antagonistic to the winners who had such overwhelming leverage that they forced Trump to quit.
Third proof: the Left looks scared rather than like empowered victors.
Fourth proof: Trump's character. He just isn't a quitter. He hates losing. And he knows Biden didn't get 81 million votes, particularly in those few counties in those six states which came in late and defied the results in 5,000 other counties nationwide. Given that the Left is pursuing Trump with fervor right now, they know Trump knows this and they know he isn't quitting.
Fifth proof: Trump's family. There is zero chance he would quit and expose his family to a lifetime of prosecution.
Sixth proof: Trump's business. His business has suffered and this will continue unless he gets the reputation of being a winner back. He hates losing in business.
Seventh proof: Trump loves this country. He knows an unbridled Left will destroy the country and Biden is moving more quickly and sharply to the Left than almost anyone had expected. No way in the world Trump lets the Left destroy the country this easily.
Eighth proof: in his book "The Art of the Deal," Trump wrote "My philosophy has always been that if you ever catch someone stealing, you have to go after him very hard, even if it costs you ten times more than he stole. Stealing is the worst." He isn't wired to just let someone steal the election from the voters and from him.
Ninth proof: as President, Trump knows all the government's secrets. There is vast power in what Trump knows about Epstein, 9/11, Iran, North Korea, China, Uranium One, Weiner's laptop, Seth Rich, Hillary's emails, JFK and the CIA, drug-running and the CIA, Benghazi, past administrations and their corruption, legislator corruption, judicial corruption, election corruption, government spending corruption and kickbacks, and on and on. Trump isn't going to sit back and get kicked, get his family kicked, and get America kicked, while holding this leverage untouched.
Something is still to come. I don't know where or when, but Trump has cards to play. He will play them. For the country's sake, for his family's sake, for his own sake. It takes a total abandonment of logic to think otherwise.
with regards to number 3 that's not really proof of anything. the left are deeply enamored with the idea of being a rebel. so when they get power and responsibility they get cognitive dissonance when the utopia they thought would come about never comes so they never believe that they really have power. that there is some greater enemy to fight, that they are still the rebel, that really secretly fascists are still in charge or whatever. they want to live in an eternal revolution because to admit that one actually is the establishment or has power is to admit that one is responsible and that the utopia promised turned into ashes in your mouth.
you can see this in stuff like the star wars sequels. when George Lucas wrote the prequels he was like "well this takes place before the empire took power so the republic will be in power in this setting" simple logic really. but in the sequels the leftist writers are so enamored with being the rebellion that they had to find some convoluted way for the good guys to be the resistance again so they made up some bullshit and never explained what happened to the republic and what they are even doing. the first order despite being a remnant of the empire are in charge of the galaxy basically again for some reason.
the left are perpetually convinced that they are always the losers and always justify their exercise of power over you as them lashing out against opressors when in fact it is they that are. and it really is quite effective. putting people in an eternal mindset that they are beset upon by some opressors at all times is really good for politics because it motivates them to always grab power and they just justify it because they dont really have power and they are just trying to be equal with those that impose upon them. and people are more loss adverse than they are happy when they gain. so telling people that they need to grab political power because they are imposed upon by cheeto hitler is more motivating when getting political power than telling people "hey lets gain some power it will be great to gain"
so point number 3 is no proof at all because that's just their default state.
