You might think that but you need information to back up your intuitions (which are wrong)
A significant amount of the total lifetime energy usage of a car is made up by it's manufacture. It is not trivial to say you should always buy something new and more efficient.
You're making arguments against something that I didn't say.
All cars have significant manufacturing costs. So saying that making batteries has energy expensive processes isn't an argument that disqualifies EVs. An EV will have much less impact on the environment over its lifetime than a gas-powered car manufactured in the same year.
