As you acknowledge, these questions all could have applied to Ron Paul in 2008 and 2012. Ron Paul skeptics in the Republican Party often did ask these questions. These questions didn't interest me then and they don't interest me now. Frankly, I find them irrelevant, but an interesting intellectual exercise. If the latter is what you are going for, I can respect that and I will respond accordingly.
GOP party leadership - Trump is challenging the candidate selection process and the damage may be irreversible. Whether Trump wins or not, the people will expect great transparency and great control of the selection process without having to go through a convoluted process. This threatens the leadership, because the leadership can be challenged directly by the people.
GOP elected officials - Trump might change the party platform. That threatens stalwarts of the current platform. They need to adjust or get voted out.
GOP money men - Trump is reducing the amount of money needed to run for the presidency. Yes, he is self-funding, but he is spending very little. He is a master of the media and despite 99% of the coverage being negative, he can always spin it in his favor. Plus, Trump is threatening the donor class through making their lobbying money irrelevant. The donor class loves their cheap labor. Trump threatens that.
