the operative phrase is "public use".
This has traditionally meant roads, forts, and other such things that are, in the end "owned" by the government (public).
In the recent decision, "public use" has been expanded to "public good" - thus anything which is ultimately "better" for the public (i.e. increased tax revenues) is now allowed.
It is a "small" but very significant change - one that effectively removes your right to own property as it can be siezed at anytime "for the public good".
And a few other things such as right of way for railroads and privately owned utilities. Still those were for highly regulated industries that are operated for public use, often with controls on profits, prices, etc.
