Correct me if I'm wrong, and move me if this is the wrong board, but in my opinion we should not focus on how to make Bitcoin do everything. Right now Bitcoin works well as a store of value, digital gold if you will. A $1 transaction fee means nothing to a $1,000,000 transaction. It does however severely cripple smaller payments, something that a cryptocurrency could be very good at.
Now it is my understanding that the point of SegWit/BU is to allow Bitcoin to be used for smaller payments by bringing that transaction fee down. Instead of making Bitcoin the jack of all trades, why not have multiple cryptocurrencies that each excel in their own areas? Leave Bitcoin exactly as is, and invest money and time into establishing a micropayment currency, a smart contract currency, etc...
Just some food for though.

You can use any other cryptocurrency as a transfer for value, it will just come with increased fees due to a need to exchange it to btc and than to fiat, if it's not possible to convert it to fiat directly (right now you can only do this for top altcoins, like Ethereum or Dash). What makes Bitcoin special is the number of nodes and mining power behind it's network, it serves as insurance that your transfer won't get hijacked, or someone will manipulate the blockchain.
