On paper it seems like that but checks and balances will kick in. If he issued an order to cut off a lot of organisations that pay money to the likes of MS and Google, do you think those businesses will allow that amount of damage to their proifts. That sort of bad press will ripple across the planet and the organisations can't survive on just the US market, they are now just as reliant on their foreign customers to survive, if Trump hurts too many of them in one go, I'm fairly certain that the likes of MS and Google will take it too court to stop the damage to their business model.
Trump thinks he is the be all and end all and that was enforced because his early executive decisions weren't challanged quick enough, now the judicary branch of the US Government has woken up a bit and is doing what it should, which is checks and balances on the executive branch. This is how the founding fathers set out their constitution, they could forsee the chance of corruption and tried to limit it as much as possible hence the 3 branches to keep each other in check.
Not saying it's perfect but that was the original idea when they formed their constitution.
