> If a zoned market solely accept Bitcoin and a good costs say 1 BTC

The problem is that nobody selling regular goods WANTS to sell his goods with a fixed bitcoin price; the volatility of bitcoin would make it easy for buyers to buy the goods only when their prices where especially low in non-crazy-volatile currency and resell the goods at a favorable price immediately. There's arbitrage there

This is true of other currencies (usd being the global reserve currency) as well though.

No sellers want the Argentine peso or Zimbabwean dollar either.
