So just strap a small bowser to your pickup or in the trunk and fill it up at the regular garage and flick two fingers to the a***oles who decided that 100LL should be 2 squids a litre..
Another great thing: 100LL is scarce in Europe, but there's always Mogas available everywhere as long as you can get to a garage. Carry one of those soft collapsible 50gal tanks in the baggage compartment, land anywhere, hitch a ride to a gas station and fill it up. Total autonomy.
That scenario is obviously applicable to only a very specific subset of the flying community.
It works if you fly from a very private site, and land back at either the same site, or another private site with a similar facility.
If you want to fly away somewhere, you will need a flying car, so you can drive to the garage to fill it up.
And it will work with very small planes only, because the amount of fuel burnt in going e.g. to southern Europe is way too much for manual handling.
How will you handle the collapsible 50 gallon tank when it has been filled up? It will weigh about 150kg.
