That would kind of defeat the purpose of Bitcoin. The main advantage is the transaction system, rather than the store of value. The transaction speed isn't really much of an issue as long as the block reward is much higher than the value of your transaction. For most modest transactions, like food and consumer goods, just seeing the transaction come across the network is good enough. It's possible to beat this, but doing so requires a large enough effort that nobody would bother doing it to get lunch when they could be getting dozens of block rewards worth thousands of times more instead. Waiting for one confirmation takes around 10 minutes and is likely to be good enough for anything of less value than buying houses and cars and other things that are 5+ figures in USD.
