I have a little hobby of spotting bits of news about how taxes are getting harder to collect on labor and capital. A good bit on that is here.
Given things like this you think that Governments would eventually be forced to tax the things that can't be off-shored, like land say.
Either that or you'll get a lot of government hysteria to push for 'global' taxation. I seem to recall the EU banging on about that.
But overall, I think that some form of LVT is going to arrive.
