I wish. But unfortunately, both synthetic fuels (e-fuels) and offsets are severely lacking in terms of actually contributing to solving the problem. We do not have enough energy to produce enough synthetic fuels to cover the same amount of oil and gas that we use today. And carbon offsets are in most cases not a reliable way to actually keep carbon out of the atmosphere long-term.
> Good luck forcing quality of life reduction as an explicit policy goal
Climate change will be the greatest quality of life reduction that humanity has ever faced.
Part of the problem is that people consider being able to travel that much as "quality of life". There is nothing in human psychology that requires us to be as mobile as we are today. In fact, it is harmful that this degree of mobility is deemed "normal" by our western culture. This has to change.

Rotating detonation engines [1] are closer to basic research than commerce. The earliest this could be technologically viable is in the 2030s; commercially, the 2050s. (That is ambitious.) At the point we might consider scaling such kit, our options will be less limited (or we’ll have consigned ourselves to doom). If they aren’t, we can choose not to use it for passenger travel.
