Every shepherd in the bible, and there were many who became prophets and kings, were essentially tabernacles.
There are situations where a single Christian has to make do with that because gathering would be impossible. Comes to mind St. John exiled by himself on the island of Patmos. (Although he did seem to get his mail delivered and picked up every so often :-)
But it isn't the norm. Do not forsake the gathering of yourselves together. Even if nonbelievers are there too.
