when you lot realise that LN is not bitcoin specific..
(1) What is the issue with that? Blockchain is not Bitcoin specific either. These are concepts that are not linked to a coin's name.
(2) Cross-chain atomic swaps work with or without Lightning.
https://arxiv.org/abs/2101.12332(3) As long as you don't exchange your 'Lightning Bitcoin' funds for 'Lightning Litecoin' funds or something else, they are always 'redeemable' for on-chain
Bitcoin funds by submitting a channel close transaction. They are always 'linked' to the channel funded with that type of coin on that type of chain. It's not that hard. It's just a different type of contract. You may be aware that the Bitcoin script language allows different types of transactions. LN channel open / close transactions are just transactions. It's no sacrilegious black magic from hell.
Not that big a deal but still interesting, the last 2 raffles that I posted in the collectables board that I gave the option of paying for with lightning were bot paid for with lightning. So people here are using it to pay when given the option.
That's nice to hear. I find myself using Lightning when it is offered, as well, since it is so convenient to spend anonymously. Since channel balances are not tracked on-chain, anything between channel open and channel close, is orders of magnitude harder to track than on-chain Bitcoin payments. So you're not going to need to mix change after every single little transaction.
lets discuss rational concepts and scenarios that actually apply to real world experiences and details and data
1. when a potential user is introduced by asking them to hand in fiat to a service and is given service database balance.. is that "bitcoin"?
In Lightning, you 'open a channel', which means you do 'lock' some balance, but you (even alone, without anyone else), with your own key, can immediately close it in the next block and 'unlock' that balance. No 'praying to someone'. That's where youre analogy is flawed.
Using keys to 'unlock' a script is actually what you do in every single Bitcoin transactions. Locking script and unlocking script. All the time. When you 'spend BTC' in a typical on-chain transaction, you actually lock Bitcoin behind a script that only the owner of the private key generating a given address, owns.

Just to reiterate: msat being rounded down can lose you at most 999msat, or 0.999sat which is worth nothing right now. Transaction fees will always be higher than 1sat.
For the record:
I'm not answering for franky because it is pointless (explained it 100 times, he must be very old or something), but for anyone reading this with some intelligence and logic, who got confused by him. If you as a reader are interested in more details about the msats, search in this thread with the right keywords, I explained it all in detail:
