Why would the party itself give voters reasons to vote against their incumbent?
Because thats how democracy is supposed to work. Candidates need to earn everyone’s vote every time theres an election. The purpose of an election is to give the population a chance to approve their reelection, it also holds them accountable. To just assume they are entitled to the full 8 years with no question or accountability is authoritarian.
That is the answer, why should they expect to keep the job if they haven’t earned it
Biden not being challenged in the primary is the Democratic Party saying “you’ve earned it”.
They are not allowing any challengers to keep his accountable.
I don’t think you understand how this works
OP’s not asking about what the incumbent expects. Why would the party itself give voters reasons to vote against their incumbent?

That’s what the general election is for.
