There is complete consensus among economists that short selling constraints are a bad idea. The effect is simply to artificially inflate prices. Typically they're used as a political tool in situations where inflating prices is the whole point.
The Greek stock exchange is a different deal. The banks are closed, without a payments system I don't see how a stock market could operate.
As for the contracts you describe, they already exist in various forms (though not denominated in bitcoin): there are single-stock futures and CFDs, but the former are completely illiquid and the latter aren't a market of their own but usually a pass-through mechanism for regulatory arbitrage.

So I get that CFD are not traded on a central exchange, and are custom investment product provided by some financial institution. So indeed not really a market. However, besides that they seems to be used by regular investor for, well, regular speculation.
