ludicrous. The meter is a length in itself, and without space you have no
meter. Undrestand this, space and time are not quantities you measure. You
use them to measure something else. For instance, your government is a

No, units are used, if you measure something.
This 'something' is what you measure (here: a distance), while the units (here: meters) belong to the measurement.
A device as simple as a ruler can measure some length. But the ruler or the inscriptions on it are not length.
