word choice - A question about the use of "everywhere" in the sentence

Recently I've stumbled upon this sentence on the internet:

Home is everywhere your heart is.

Somehow it doesn't seem right to me. If I had to convey the same meaning, I would write something like this:

Home is wherever your heart is.

Or this:

Home is everywhere where your heart is.

Could you please clarify whether I'm right or not.

Answer

The definition of everywhere permits the first example of the OP:

adverb

1.0 In or to all places:
I’ve looked everywhere
everywhere she went she was feted

---

The definition of wherever includes the second example:

relative adverb

1.0 In or to whatever place (emphasizing a lack of restriction):
meet me wherever you like

1.1 In all places; regardless of where:

---

Where is used as a relative adverb as suggested by the third example:

2.0 The place or situation in which:
this is where I live

---

All four of the following constructions would be grammatically acceptable with slightly different nuances. The first would be idiomatic, while the fourth would be slightly redundant:

• Home is where the heart is.
  Meaning: Home is the place in which the heart is.


• Home is wherever the heart is.
  Meaning: Home is in whatever place the heart is.


• Home is everywhere the heart is.
  Meaning: Home is in all places the heart is.


• Home is everywhere where the heart is.
  Meaning: Home is in all places where the heart is.

If the original author intended to emphasize all places, then everywhere is the right selection.
