I have no idea what you mean. The executive branch didn't routinely ignore court orders and disregard the constraints set out in the Constitution before that date. The government broke laws, but it was a scandal when it did and people -- the perpetrators, not random civil servants doing the jobs they were hired to do -- got fired for it and sometimes jailed. Now it's just another day that ends in y.
In theory Biden could have taken the SCOTUS grant of immunity to disregard the Constitution as Musk and Trump are doing, but he didn't. Trump's taking power was a step change.
We still have laws, but the executive branch under Musk/Trump regards them as mere words on a page. They bind others, not them.
