英文摘要：
Recently, the French Senate approved a law that imposes a 3% tax on revenue generated from digital services by companies above a certain size. While there is a lot of political debate about economic consequences of this action, it is actually interesting to reverse the question: We consider the long-term implications of an economy with no such digital tax. More generally, we can think of digital services as a special case of products with low or zero cost of transportation. With basic economic models we show that a market with no transportation costs is prone to monopolization as minuscule, random differences in quality are rewarded disproportionally. We then propose a distance-based tax to counter-balance the tendencies of random centralisation. Unlike a tax that scales with physical (cardinal) distance, a ranked (ordinal) distance tax leverages the benefits of digitalization while maintaining a stable economy.

中文摘要：
最近，法国参议院通过了一项法律，对一定规模以上公司的数字服务收入征收3%的税。虽然关于这一行动的经济后果有很多政治辩论，但事实上，扭转这个问题很有趣：我们考虑的是一个没有这种数字税收的经济的长期影响。更一般地说，我们可以将数字服务视为运输成本低或零的产品的特例。通过基本的经济模型，我们证明了一个没有运输成本的市场很容易被垄断，因为质量上的随机差异很小，会得到不成比例的回报。然后，我们提出了一种基于距离的税收来平衡随机集中的趋势。与按物理（基数）距离分级的税收不同，分级（顺序）距离税利用了数字化的好处，同时保持了稳定的经济。
