I agree with most of this, but we keep finding clever ways to knock down sectors that had seemed impossible to electrify. For instance, FleetZero claims to have a practical approach for global shipping [1]. It's not yet proven, but I haven't seen a serious counter-argument.
Even for jet travel, we may be able to whittle away at the problem with electric planes (or trains!) for short routes, and hydrogen for medium routes. Long routes may have to rely on artificial carbon-based fuels, as you say.
