Economic rent isn't the same as just paying landlords rent, though it's related. Economic rent is basically you profiting from owning stuff and doing nothing. It's a pure wealth transfer

https://en.wikipedia.org/wiki/Rent-seeking

Rent seeking behavior is when you try to acquire more wealth without creating more wealth. This would include behaviors like regulatory capture, or raising housing rents or other necessary goods to whatever the populace is capable of paying because they have either little alternatives or switching costs are prohibitive. Monopolies, IP law (and abuse thereof), and cases like Apple prohibiting other app stores are all examples of rent seeking behavior as well.

A nice quote from the first article on Land Value Taxes and why this is directly relevant.

> "Henry George, best known for his proposal for a single tax on land, defines rent as "the part of the produce that accrues to the owners of land (or other natural capabilities) by virtue of ownership" and as "the share of wealth given to landowners because they have an exclusive right to the use of those natural capabilities."

It is a generally agreed upon problem, going all the way back to adam smith. It's not possible to have a self consistent economic ideology that does otherwise. You get some radical free market capitalists who think otherwise, but if it were up to them we'd all be living in the United States of Standard Oil by now. They're safe to ignore.

The solution to this problem is not clear at all and varies dramatically by ideologies.
