Putting aside being rude to the flight crew, something that is never justified, OP simply misapprehends the system.

DL Operations makes the decision on holding flights, not some GA at NRT. The strong presumption is against holding flights for a whole variety of reasons. The most likely reason is that the onward flight was at risk of an oversell and when OP and his 11 comrades missed the T-30 deadline, they were off-loaded and the SB's loaded. Why hold an aircraft just so OP can run for it and find that his seat is gone?

If this were some massive 2-day mess, OP might see something in the 20K miles range. As it is, where he is acommodated with a PITA but workable service recovery, he will likely see a token 5K-10K miles as a gesture.

As to the snark to the Captain. That's just plain silly. The delay was caused by the fuel line, not the Captain. He is the one who spotted the problem. Perhaps he should have ignored it and flown anyway. Maybe you would have made it to NRT, maybe not. Did he really laugh at you or with you? Who knows. But, when you spend your life the way air crews do and get treated the way this one was, you either laugh or cry.
