I assume this 497 BTC output is unspendable?

Well MtGox wasn't the only one to do it.  2609.36304319 BTC over the years due to this single malformed template isn't a small chunk of change.  It just struck me as strange as these 23 outputs represents the majority of the "custom" scripts in the UTXO and they all are the same exact mistake.

They were all within a couple hours of each other AFAIK and all by MTGOX.  Am I incorrect?

That's all gox's coins. Their retard CEO admitted that. Google this forum should find that

Imagine the situation when top-10 mining pools will accept this protocol change in 4 years from today.
There will be split of network in ~2018.
I think that the majority of users will follow the pool-owners

No, they won't. They'd have no economic incentive to. If a cartel of a few individuals can change bitcoin at will, then bitcoin loses its only redeeming feature and becomes a very expensive, less usable version of paypal. There is absolutely no way that any central party can mandate controversial hard-fork changes to the bitcoin protocol, no matter their hashrate.

Give me a seed of your hope in this.
I see a lot of absurd (for my opinion of course) things in real world created by crowd.
Why bitcoin is free of it?

Because that will make bitcoin worthless

there are nearly 2mln coins that have never been moved ever since being mined - most of them from pre-2011 times.
I'd say, most likely they are lost - or at least half of them.
so by these numbers, who would even care about some 500btc?
lots of coins have been lost in the past years, and many will be lost each new year.
in fact, if you think about it, getting lost some day is the final point of each bitcoin that's been or going to be mined.
it's all just a matter of time.
essentially they get to die like everything

I think attempting to return the coins to Mt Gox would probably be hard to get consensus behind, but as it's never been tried nobody really knows for sure.

Respawning those coins into the money supply is probably a lot less controversial and I did consider the idea a few times before, bit it's also not clear it's worth the effort and complexity. Actually I'd say it's not.

Both are very bad ideas. Any hardfork related to money supply will destroy the value of bitcoin.

Also, we never know if there was any secret deal between Mark and someone, and these coins were used as a proof-of-burn.

Finally, these unspendable UTXO could be safely pruned.
