For a desktop yes. You can dock it and forget that it's not a regular Linux desktop. Especially if it means Python and JS, you don't need much power for that.
For a laptop not so much, because you'll need to bring screen+keyboard+mouse and everything to plug them so the portability aspect seriously suffers.
You can deploy open source software or your own apps even on big tech infrastructure, on your own domain.
The problem isn't infrastructure, it's that access to content isn't decentralized any more. Access to content is reliant on Google search or social media algorithms (who decide what to promote).
