For the average pleb using a software wallet, your sats flow and time horizons should be as follows:
Lightning <> Liquid -> Bitcoin
days -> months -> years
Stack smart, hodl Liquid in the mid-term and occasionally swap to Lightning for daily use, then to mainchain when fees are low for long-term savings.
More educators and Bitcoiners should be onboarding newbies to Liquid first, with Lightning as a next step, imho.
It's not just easier from a technical view to onboard to Liquid these days given the high-fee enviro but conceptually and in terms of natural learning progression it makes the most sense.
Sidechains are a far more digestible concept than payment channels/liquidity mgmt after first learning about Bitcoin and blockchains.
