Nice reply, you really touched all the important issues, and like I said before in my replies, I essentially agree with your views.
The one thing I don't fully agree with is the price to set when transfer listing players (and this isn't even related to the main topic itself). I don't know how this goes in the top divisions, but for the kind of players I buy or sell, listing them at a low price has the risk of ending up with an "unfair" bid, but it also helps gather more bidders. You may notice that when players come on the TL as FA, some players place lots of 1k bids to keep tabs on the players, I have done it myself. If one starts with a higher asking price, fewer people may notice it, and there's a bigger chance the player will go unnoticed if people set a low limit because of the newly arrived free agents.
Other than that, the idea of having a warning sign saying "Warning: the player owner is bidding on the player!" could be introduced, but I don't see much need for it, to be honest. If the bidders notice, they should stop bidding. If they don't and the price is not overblown, they're free to keep bidding. If the price goes over any reasonable valuation and someone still bids, then that's just throwing money away.
