I think the main problem here is that Tesla packages almost everything and make it unavailable as a single option. Most car companies make packages of several options, so instead of choosing the most common features they bundle it up and make it a package with some discount. But you can still choose to have one of those options without getting the entire package. There is no technical reason to not allow the customer to choose all the options seperately or as a package, so Tesla really should reconsider if this is the best way. Sure the customers that must have the electrical trunk will pay the extra 5000 USD just to get it, but the person who thinks it's a nice to have will not pay 5000 USD extra, and instead they lose a sale for electrical trunk. However none of these customers will be fully satisfied, one had to pay for a lot of stuff they didn't want, and one didn't get what they wanted, even though they were willing to pay a reasonable amount to get it.
