It's essential to get rid of Physical barriers to exchange, but it becomes possible only if regulatory bodies agree or accept for such a free market to co-exist with the existing banking systems. The true test of strength for Bitcoin would be its cross border transferability without having to worry about the TSA at the airport checking your luggage and laptops for any hidden paper money that you're carrying over a limit that has been specified or allowed. Also most of those companies are setting up blockchains to privately benefit themselves and only their customers, not necesarily a large proportion of the population. Like for example, Starbucks has its own cryptocurrency and this is okay for coffee buyers, and it kind of acts as a replacement for tokens or coupons that people buy to purchase coffee, but I'm not sure if people would exchange this token as much like Bitcoins would be exchange between people. These token based blockchain currencies are just similar to exchanging Amazon gift cards which is done is small amounts.

Mostly the need is felt for regulation of cryptocurrencies so that it can be continued to be freely used without having to worry about legal issues or jail terms. There needs to be a free market for crypto enthusiasts as this would help people maintain their personal privacy for the transactions that they make, as compared to making payments using their credit cards or the traditional banking system. Lets hope that regulation happens in a way that doesn't put barriers or extreme limits on crypto trades, and allows for a free market to prevail and traditional banks to realize its potential and to value peoples privacy.
