All you've done is created a straw man. No one is arguing that the app store shouldn't exist or that if you choose to you shouldn't be allowed to use it exclusively. The argument is that alternatives should be allowed to exist and that people should be allowed to install whatever software they like on the devices they own. If other app stores or modes of installation exist, that ruins nothing for you. You can just ignore them and go on as you do now.
