I'll explain. You probably wouln't collect much in land taxes from these large tech companies.

But why this eagerness to tax them so much in the first place? Because of unfairness relative to smaller companies and employees who carry the whole burden of taxation and those tech giants pay close to zero.

In land based tax system you wouldn't collect much from large tech, but you wouldn't collect much from small businesses and employees either. Fairness achieved.

Now you might ask, wouldn't we be really short in tax revenues if we kept only land taxation? The answer is pretty surprising that it would likely collect even more revenue that current system based on sales tax, income, vat, etc., but I encourage the careful reader to study land based tax systems on their own to discover their simplicity and beauty.

I'll just hint that there is so much value stored in real estate (of which the biggest part is its location value, ie. land) that it dwarfs world stock and bond markets together. So just imagine making it a base for a tax.
