You're missing the forest for the trees.

This isn't about an individual's right to free movement. It is about keeping employers honest about where their employees work and making sure they are paying their fair share of local taxes.

Groups of people put a strain on the local resources, we need those local taxes to fund those things.

If individuals were allowed to live somewhere and dodge the local taxes, every large company would use this to their advantage. Suddenly campuses of workers would all now be "remote" employees from their offices in some tax friendly area. This would put an undo strain on the local tax base who are now having to foot the tax bill for those not paying their share.
