If the browser has actual native support for interacting with EVM chains and IPFS, supporting user-friendly features like ENS or UD domains, allowing anyone to publish a page or an app in a decentralized manner, it certainly has value especially with the current centralization (e.g. FB/Twitter/Google: censorship, banks: control over money etc).

If this stack gives the control over data back to the users, there will be some value. But I assume, even with this stack there will again be tendencies towards centralization driven by convenience, efficiency and simply bargaining power...
