It's true that when a French person comes to your country to buy your product, then goes back to France, the burden is on them to pay the relevant customs and taxes. On the other hand, I would argue that the market of people who would come to your country to buy your product is significantly smaller than the market of people who buy it on the internet and have it delivered---and it's fairly typical for companies sending products to France to be asked to collect any duties, customs and taxes from the purchaser. Why would electronic delivery be different ?
