Yes,
King Naugladur, we agree on some things and disagree on others. It appears that while we agree that Mîm has a claim on Nargothrond, we disagree about his claim on the hoard, I claiming that he has none, it being Finrod's or his family's.
In terms of the issue of compensation:
In my humble opinion, had Turin paid the compensation, it would be mentioned. It is not mentioned if, during the brief success of the Dor-Cuarthol, Turin came in possession of treasure, but I deem it unlikely, since he was far more interested in military opposition to the Orcs of Morgoth and not wealth. On the other hand, Mim's plea for Turin not to be killed can be traced back to the great respect the Dwarf felt for him. It is mentioned that, during his first winter at the Bar-en-Danwedh, Turin listened very much to Mim's lore and the tales of his life. Since all Dwarves are normally keeping such things to themselves, we can surmise that Mim held Turin in very high esteem.
You may be right, for the reasons you gave, that Túrin was not in a position to pay the promised compensation to Mîm before he was captured. The dwarf may have asked for Túrin's life to be spared due to having respect for him. However, this has nothing to do with Finrod's hoard, which wasn't Túrin's. Also, while Túrin gave his word to Mîm, Húrin didn't, so was not part of that agreement.
Regarding the sons of Fëanor:
Coming to the behavior of Celegorm and Curufin, I do agree that Maedhros should have acted more responsibly. The lack of an apology was wrong, but this does not eliminate the fact that Thingol could not lay a valid claim on the Silmaril. Both sides committed gross errors, which resulted in the Second Kinslaying.
We agree that Thingol should have handed the Silmaril over, as it wasn't his. Also, the brothers should have acted far more diplomatically towards him regarding that jewel, which
might have produced a better result.
