Not really. To me it seems like you're latching onto a single not so relevant point of the difference. I could use the same argument for why serfdom is not at all equivalent to debt slavery because you can choose to grow the land however you like.
It's not true that all white collar workers can switch jobs every few years. Some white collar workers in the US can, and even then with asterisks (non-competes, wage fixing, etc...)
The biggest reason why serfs would stop moving is to have children and a wife.
