Still don't understand how would you spend 0.00001 if you cant you can't even open a channel with that amount.
With LN, it will likely be difficult to spend your
last 0.00001
BTC, however once you have a channel open, it will be fairly cheep to spend 0.00001
BTC if you have a significant additional balance within the channel. This is an improvement from the current state of Bitcoin because it is (and always has been for this specific example) prohibitively expensive to spend 0.00001
BTC.
Now you can't spend it because fees on chain are bigger than that. Will opening channels be cheaper in the future?
The cost of on-chain transactions will likely increase.
