What you are forgetting is that diesel engines only work with diesel and gasoline ones only work with gasoline. This creates a natural incentive for the customers to not mix this up.
In the e-fuel vs trad-fuel story you do not have that incentive.
What you DO have, is an incentive to actually do the switch. Projections put e-fuel production costs at a 1500% premium over fossil fuels and wide spread availability is actually a hard scientific problem as even the announced global production capacity* of e-fuels is only enough for a few thousand vehicles.
* Apparently, to date, the biggest portion of announced e-fuel production misses either an energy provider or financial backing or both.
