Of course there is an alternative, but how many people even know what Lightning Network is and how to use it, even on this forum? In addition, in order to use LN you have to open a channel, and to do that you have to pay an on-chain fee, which is again a problem when the fees increase significantly. What will happen if someone comes up with a way to make LN transactions disadvantageous in any way - the new LN?
Lightning network is online. It is good for small amount of money. So why need to open a channel? You can use some wallets that have a channel for you. All you will need to do is to download their wallet, open the wallet and do backups and start using lightning network without opening any channel. In addition, those wallets that have their own channel are very easy to use. They are even the ones that make lightning network adoption to be increasing.
