Frankly, neither #2 nor #3 apply to a pile of cash in a safe deposit box (and who loans almost twice the median income to someone?!), and #5 is illegal.
But yes, big pile of cash is definitely a bad excuse for a search and a worse excuse for a seizure.
As far as number 5, you can't assume that's illegal either. I have a family member who's ex wife continues to commit identity theft and cause headaches for him 5 years after the divorce is over.
In that case, it would also be illegal.

Okay? So he keeps his money in cash in a safe deposit box? Doubt.
It'd only be illegal if they weren't paying taxes on it or otherwise not reporting it for other purposes. Having a giant pile of cash because I don't like my bank auto reporting my money in and of itself isn't evidence of anything.
Only if that's an attempt to evade legal requirements, rather than (for example) moving personal money out of accounts that the ex-spouse has access to.
