Because servicing and spare parts are a huge business. And unless some one is specifically looking to disrupt that part of the business. Its in their interest to keep the charges for something like that high.
I believe you misunderstood me. My original question was why serf was okay with an electric car having this lack or repairability vs one with an ICE when the specific repairability question involves something like realigning headlights which has nothing to do with ICE or not. Of course you're right that manufacturers are more than happy to extract extra money from consumers through such servicing agreements, but that has nothing to do with my question. Besides that reasoning applies to manufactures of ICE vehicles as well so your point is honestly totally irrelevant.
