Is it a core requirement of how LN functions that any time state of the channel can be included in the Bitcoin blockchain or is it just because LN is not yet fully developed. Hopefully a clever solution can be found to fix this flaw.

Older LN channel state is cryptographically valid the same way as newer state. The only incentive not to trying to add older LN channel state to Bitcoin blockchain is the other party with newer state can punish it by getting all such channel coins for themselves - but only if the tansaction can be added to Bitcoin blockchain in timelly manner (you can set the time how long your fine to have stuck your LN coins when opening the channel - this corresponds to the time available to react for having confirmed tansaction in Bitcoin blockchain should this scenario happen). This has theoretical attack vector possible with big LN hubs and congested Bitcoin - like with exchange hacks, it is only matter of time when such attack become reality one day.

Tx again - so think about all the possible attacks that are still unknown (I piss at ANY code reading and testnets - that's NO production proof / even SW in LTC is a proof of no-use)) ? How many options you had attacking Bitcoin over its first 1-3 years?

We should really better get back 'conservative' and get Bitcoin stronger and risk-free with highest reputation than ever! Scale the thing up to the sky and pay the miners for our all security - or scam them and you pay later by loosing your coins.

And if you still think you need new toys -> get scammed in the altcoin sections!

Listen to expert Matt Corallo at 35Min to a question of a friend of mine about the security issues - dodgy...
