You can't use lightning network without opening a channel. Opening a channel requires making an on-chain transaction which most of the world can't afford. Lightning network is absolutely useless on BTC. Add lightning network to a chain that isn't crippled then let's talk.
I use the lightning network almost daily and I’ve never done that. I just use a wallet that is lightning capable and that’s it.
How exactly are you using the lightning network without an initial transaction to charge up your metaphorical gift card?
You could use a custodial solution untill you stack enough to get a channel of your own.
