Trump using the Obama and Biden precedents of proceeding until all appeals (up to the Supreme Court) is logical.
He still has appointments to get through, and doesnt want to spook the Rinos yet is my guess. Also to show that he tried to "do the right thing", if we are still here with court bullshit in 2 months then I will agree Trump is retarded for not taking plans for the most obvious counter steps the Dems would do ever.
Picking these fights seems purposeful, he is doing it at the apex of his political mandate and topics the public will side with him on. If the Dem's were smart they would be focusing on shit like Birthright citizen, (a topic that parts of of Trumps coalition may turn on him on about) but by making the initial battles about US fucking AID and tranny beauty pageant and clear bribery, the public will take his side.
Roberts is a RINO cuck, but he also knows the Supreme Court is hanging on by a thread politically and its only Republican support that is keeping it politically legitimate. If he confirms that "yes random Hawaii judges are equal to a president" then all that happens is the judicial branch loses all of its power. He knows this.
