And the other side of the same coin is that a GOP majority of fewer that 60 (like-minded) can't get what it wants (passed), either.
When the GOP has a majority or a supermajority, it tends to pass MORE laws, and to futher increase the encroach of the federal government into personal matters. Big spenders, big borrowers, etc.
Until the GOP adopts a fairly radical agenda (ala Reagan, the government is the problem), they are more useful in the minority, in the Senate.
I think that you are rationalizing a very bad idea. The the political world, it’s always better to be in charge than it is to be in the minority. If you happen to be in the minority then you try to make the best of a bad situation. I’m sure that the Democrats will be more than happy to take you up on an offer of surrender.
