I hear you, I'm currently running my own private relay as a backup, but that's just one part of it.
Using a paid relay does make sense, it can help you reach more people and discover more people as well. Nostr.wine also channels your content to other countries and popular relays, so that's an additional perk.
You can always turn the public and private relays on and off, so isn't like you will lose your freedom on this :)
