Not everyone has to buy that separately. For example, I have plenty of sd cards laying around. For the charger you are probably right due to the rpi not working with every usbc adapter, but that's 10 euros. You selected the 4GB one, but if you select the 2GB or 1GB version things get cheaper too. I think they are great value for a very reasonable price.
