That doesn’t make Pelosi constitutionally equal to Trump.
Putting the other arguments aside and assuming that the Executive and Legislative Branches have absolutely equal power, the President IS the executive branch. He controls it by his say so.
Pelosi is the leader of one of the two houses of the legislative branch. She can enact nothing on her own. As you are aware, she must get a majority of her House to approve legislation, have the Senate, which is currently in the hands of the other party and unlikely to approve her directives, approve it with a majority (more likely 60 votes) and then the President again has to approve it. If he does not, she needs 2/3ds of her House and again 2/3ds of the Senate.
I think it is clear that the Constitution does not say that she is equal to the President anymore than Mike Pence, by virtue of being President of the Senate, is equal to the President. And neither can say that they are 50% equal to the President because unlike either of them, the President does not rely on a vote to conduct executive functions.
