I highlighted the key word for you.
Yes, if you're simply already owning a stake of a size that never existed in NXT - and you additionally simply scam yourself into 41% more - and then simply buy 100% of all that value in shorts, and then simply gain another 30% so you cover your costs. Then you can attack.
Why did no one think of that before?

10% is needed for an attack. Re-read the research paper sir. None of that 10% needs to be owned either as we have discussed.

Which paper? The papers say there is no viable 10% attack.
There also is no 10% whale or exchange in NXT - you crossing it out doesn't make a fact disappear, you know.

We are discussing a specific scenario where attacking PoS is far less risky than a similar attack with PoW.

Not sure what you mean with "we".
We know that PoW would be easier to attack if you magically get a 10% stake - since that would likely buy you 51% of all mining.

Clearly you didn't because you still don't even know what the term "nothing" means.

You also understand that in physics "nothing" does not have the same connotation as within philosophy?

Physics? Really? I hope you're just kidding.

Vitalik is going with PoW for ethereum despite all his research into TaPoS and weak subjectivity. Why?

You're lying, or again proving that you're not even reading the links you provide.
And since you're wrong: You should answer the "why" question yourself.

Whether he uses straight PoW or PoW/TaPoS the point to consider is that he has thoroughly studied the vulnerabilities within PoS variations and deems them to have insufficient security alone without PoW.

A small proof of work component is exactly what NXT (and Blackcoin... and others) do.
Again, it would help if you read what you link - would waste less of everyone's time.
