From what I've heard, he traveled via a cruise ship bound for Britain by putting that into luggage in a concealed compartment.

I remember reading an article from Australia where a woman requested to withdraw a five figure sum (over 20k) in cash from her own bank account but they're like "sorry, we can't do that" making excuses on the way of "need proof on how you acquired such money", even though she provided all the evidence, they still refused anyway. She was like "WTF? It's my own money!" so there's a possibility that banks dictate how much one can withdraw.

No shop accepts them. ATMs give out 50 euro notes

Will electronic stores accept either 100 or 200€ bills when purchasing an iPhone for 1500€ upon paying in cash? Also, can you pay only with 200€ (x30) only in physical currency when purchasing a 8K TV that may be 6000€.

That's where cash serves a purpose, as a payment method during that kind of scenario.

I've heard cases regarding civil asset forfeiture with citizens traveling domestically having large amounts still got it confiscated by DEA agents due to suspicion of criminal activity. So in knowing that, will they still seize non-USD currency: 30,000,000 Rials (~$78,125,000) in cash even though it's being withdrawn from an Omani bank and it's the individual's own money just carried out in multiple stacks.

100€ is not that common

But, can you visit a bank enquiring if they stockpile that denomination? (Same with 200 or 500€ bills) Like, "can I withdraw 5000€ in cash from my account consisting of only 100 & 200€ bills?"

Just have this instead, it's much more compact (~$1.2k in your pocket) -

Have you ever read subtitles (日本語字幕) without pausing? Whenever I watch a non-Japanese movie, I just enable JP subs and you need a very good grasp on reading Kanji in real time since you're reading translated dialog, and sometimes you can notice translation mistakes if you know where to look based on visual context within the scene. For Japanese movies: I sometimes enable closed captions to understand clearly what they're saying.

There are individuals who "copy existing bills exchanging those for legitimate ones with different serial numbers" (counterfeit) and that actually happens, like for example: North Korea is infamous for producing convincing clones of US$100 bills that look believeable.

whats with these Euros? Why cant they just accept dollars here

Little did they know, Euro is WORTH MORE than US Dollars at face value as reflected by the exchange rate. A 200€ ($235) note is higher than $100, and there is a 500€ ($589) note (although no longer in circulation) but nevertheless, it still exists & definitely more than $100.

romaji

Relying too much on romaji is bad, try to read using furigana (which is a hiragana transliteration on top of Kanji).

I mean, more of a friends of friends or room mate (not a complete stranger). Like the memes equivalent to "kid uses mom's CC to spend on fortnite skins" but it's more on your own circle, withdrawing large sums is too obvious. So, an individual will only make their own family members or friends withdraw small amounts at a time at separate intervals (every few months).

The withdrawal can be done by using another person's card (instead of your own) making it look like they did the transaction (think of skimming devices implanted onto ATMs that are compromised). However it's a grey area.

who uses cash nowadays

Cash exists for a reason such as in the case of power outages, most payment systems are down in that type of scenario, since those are reliant on electricity so cash is a back up.

To put into perspective: there’s Beluga (a type of caviar) in Switzerland that costs Fr. 1000 or over 1.2k USD, so a Fr. 1000 bill will be accepted at luxury or high end stores.

I’ve seen a video where a German woman wanted to buy flowers with that bill but was told they don’t have enough change to hand back hence why they politely refused despite the fact this bill exists and is legal tender.

It's a typo, sorry. Anyway, even though the 500€ note is considered obscure: can high end stores accept that as payment? Euros makes USD look cheap since most of their physical notes from the USD are the same size & look bland. Euro bank notes look colorful in comparison. I would say it's difficult to counterfeit Euro than US Dollars (especially the $100 bill is prone to fakes).
