Best way to do it I've ever seen is the automated transactions tax, whereby you replace most taxes with a small percentage taken on every financial transaction (plus a larger one when converting to/from cash to account for the black economy). It's progressive because poor people will only pay twice (once on their salary/benefits, once when buying stuff), whereas rich people will pay several times when moving money ar…

Expect a new class of companies to spring up overnight that are dedicated to bundling transactions to avoid this new tax. For instance, I could make a single transaction to my broker that covered all of my expected expenditures for the month, and that broker would then disburse it to my payees, bundling it with funds from other payers to avoid the tax on the other end. I am strongly in favor of a tax on all stock mar…

Tax law already handles much more complex schemes. Admittedly nowhere near perfectly, but then this scheme being simple frees up resources for policing, and the tax code being much simpler makes it less easy to exploit.

Why tax the income side when you could just tax the consumption side?

For simplicity's sake. All transactions are taxed equally, no way to evade it by making false or borderline claims about the nature of exchange, and no resource have to be wasted on optimizing or litigating them.

Taxing consumption is regressive; Bill Gates can't eat that many more hamburgers than the average person.

Write everyone a cheque. Taxing income is quite regressive too: it’s how people with nothing can survive.

Taxing income at a few % as this scheme intends is not regressive.

What if most of the aircraft was hydrogen tank or bag? Then it could use the hydrogen for some of its lift! We can call it an "airship". Or compress the hydrogen, but then you have 700 PSI handling issues and the tanks have to be very strong.

> We can call it an "airship". Yeah, let's make a huge one and call it the Hindenburg! That sounds like a foolproof plan.

Too bad that there hasn't been decades of materials science improvements, including and in particular to handling flammable materials, between some highly propagandized disaster and today.~

(Almost every modern cruise ship is bigger than the Titanic, imagine if people acted like the Titanic was the last word on how big a cruise ship could get.)

Or just use hydrogen, it's a much denser energy storage medium, and airflight is less cost sensitive than ground transportation.

> just use hydrogen At that point, why not package the hydrogen on a carbon chain...oh wait. A lot of these schemes compare poorly against synthetic jet fuel manufactured from atmospheric carbon.

Likely the issue is cost. We can make liquid H2 pretty cheaply these days. We don't know if synfuel can get close to that price.
