Gary North has an interesting piece out today [3]. Unlike me, he is interested in growing churches, but the principle is good: do it underground, quietly. This is how TOLFA [4] works; no parades, no meetings, no speeches, no campaigns - just one-to-one, exponential replication.
Quote: "If you can’t find it, you cannot tax it. If you cannot find it, you cannot regulate it. If you cannot find it, you cannot subsidize it. If you cannot tax it or regulate it or subsidize it, the state cannot suppress it. It’s simple. And it is working, just as it worked from Nero to Diocletian."
