Not just easier, but preferable. When big companies (or rather new companies that can get big, as the old ones probably won't change anyway) start preferring P2P infrastructure to conduct their business and offer their services, we'll know there's no going back from a decentralized Internet.
If you want to work for an open internet, this is the key thing. For open to be the default, it should be dramatically easier to implement a new thing using p2p or on a blockchain than with centralized services.
