I think that rationale would apply to some other countries, but not all. For example, Japan should want to maintain a viable semiconductor manufacturing capacity (and might be at risk, currently). Now obviously Luxembourg cannot. Where exactly in between the size of Japan and Luxembourg one draws the line is a tough question, but probably western Europe has at least a couple countries (Germany, France, UK) who are big enough. Lower-income countries like Brazil, South Africa, Argentina, India probably want to, but may have to work their way up to that; it's an expensive business to be in. I notice that China has absolutely made it a top priority to try to get into this, despite having some difficulty doing so.
