How sure are you that 100% of all miners and all mining pools in the entire world will honor the agreement not to put such transactions into the chain in the first place?

I don't believe it would require 100% of all miners. A simple majority, a bit over 50% of the hashing power, should suffice, right?

If even one miner somewhere in the world puts such a transaction into the blockchain, how would you suggest the remaining miners handle the situation? Do they ignore that block, or do they accept it and build on top of it?

I would suggest they drop it. That way it wouldn't pay to waste a mined block including such a transaction. Since miners choose which transactions are included in the block, they needed include them in the first place.

So your solution is for a group of miners to "solve" a potential theft by stealing bitcoins from other miners?

Sorry, no thanks. Good luck getting a consensus on this. Almost certainly it would result in those miners whose blocks are being dropped deciding to drop the blocks from the group you approve of. This would split the bitcoin blockchain. There would be 2 bitcoins. Those that embrace fungibilty of currency, and those that want a cartel that can independently decide whose transactions are "good enough" for their system.

I can tell you which "bitcoin" I'd choose. I wish you luck with yours.
