Honestly its only worth it, if its a combined effort to revive local production while make sure that the taxpayer directly benefits from the billions in public funding that the companies get.
Public money = public product and research results
Trade secrets dont really need to be protected anymore these days, because this level of production is only possible with huuge preexisting capital or public funding anyways. If you remove the unregulated import flooding then there wont be any internal competition, so we need to compensate for that by at least stopping the intelectual property / patent disaster.
