So this is our system now, president makes a law, congress tries to pass a law to make what president wants illegal, president vetos it, thus presidential mandate is now law?

Sadly, that seems accurate.

But that rule - which is not a law, but has the effect of one - can be administratively repealed the instant another administration takes power.

There are many rules that Trump or Bush could have simply voided on day 1. Trump did take out a few but of course Bush just added to them.
