Should I buy my PlayStation 4 games from the PS Store from now on with Sony's new PS Now service?

So today I was reading about Sony's new PlayStation Now service that they will be rolling out as a beta in the US this year and it got me thinking, should I now purchase all my future PlayStation 4 games from the PS Store instead of purchasing the game disc so it is on my account ready for when the streaming service finally supports PS4 games? I imagine that the streaming service will be like iTunes Match as well as Netflix?
