Mastodon simply cannot be that user centric because the user can only control the subset of the Fediverse that your instance is able and allowed to see. Given that single user instances are largely nonviable due to the abundance of blocking in the 'verse in lieu of adequate spam controls, which ActivityPub fundamentally lacks, your choice of homeserver matters more than anything. And of course, there's no good way to choose one as a new user. Most newcomers will simply give up when faced with the choice. Even with great interest I've gotten stuck at this stage multiple times, myself. No homeserver seems welcoming, and they're all a little culty.
HN looks at the federated model and thinks about how much control the homeserver operator has and imagine themselves in that position as a "user" when the truth is that each homeserver is a small fiefdom run by a dictator and users have even less control over what they see there than they do in the corporate networks
I used a single user instance, and it's perfectly viable. If anything it's less hassle with respect to blocks.
Relays can also easily mitigate the issue you describe, as can an algo provider that simply boost all entries it puts in your feed.
