That's a ridiculous statement.

When you tell someone the grocery store is 5 mn away, you're expressing time, not distance, because you think they're interested in the time, not distance.

Yet you don't convert meters to minutes when you're telling someone how high they should build a wall. And you don't say "drill a hole 1/2000000 minutes by car wide".

That's the point of having a well-organized system of units, you can clearly express whatever you need to, always using the same system, and anyone who knows the system will understand it regardless of context.

Not being able to express distance as a separate concept is clearly inferior, since in our system we can express time, like in your example, but we can also express distance precisely when needed.
