Governments can keep companies working for as long as they want. Usually that makes them less competitive over time though and it is all done at the cost of the tax-payer and adjacent industries.

The Chaebol model of Korea is a way to spin it while avoiding the less competitive part by forcing the companies to compete internationally while keeping the domestic market locked into the Chaebol offering.

For example the US gov could force (or subsidize) all datacenters in the US to use intel chips made in intel foundries located in the US. But on the international market intel would need to compete with its rivals.

This is all theoretically possible, but very hard to pull off politically. And it is not necessarily good for the country long term and certainly a tax to the country citizens/adjacent-companies in the short term.
