The legislative and judicial branches are both expected to hold the executive accountable if it breaks the law. If that doesn't happen our system is fundamentally broken, we might as well throw it out and start over.
Is there any democratic system that is safe from democratically voting to dissolve the democracy and replace it with whatever autocracy/kakistocracy/oligarchy we've got now?
No, every country is one election away from this shit-show.
Which is why under no circumstances you should ever elect anyone who will send yours in that direction. Canadians, take note, the CPC only detached its lips from Trump's backside because they needed to come up for air.
At minimum, don't elect people who staged failed coups. They and their supporters will not ever act like they are bound by law.
The executive branch has blatantly violated numerous laws but so far they have still obeyed court orders which explicitly required them to follow those laws. The real Constitutional crisis will come if they decide to openly defy a federal court order.
I would also note that while the current Trump administration has broken federal laws at an accelerated rate, the previous Biden administration did much the same thing on a smaller scale. People here on HN frequently make excuses for Biden's illegal student loan forgiveness program because they liked the results but if we want to preserve the rule of law then it needs to apply to every program. In the long run allowing unchecked growth of executive branch power and the administrative state will be bad for everyone.

Biden didn't do anything you suggest. You're consuming the propaganda. George Bush made it so that Federal workers with student loans could get them discharged at X years of service. X just happened to fall into Trump's first term.
Trump broke the promise made to people doing their civic duty, Biden repaired it.
Biden never took on more authority than what was established almost two decades ago.
Biden was absolutely trying to cancel, or partially pay for, any federally backed loans and pell grants [1]. It wasn't limited only to federal employees with student debt.
