No, dialup was still common in the early days of Steam, game content was not largely being delivered as downloads yet and discs were still useful because it could not yet be taken for grated that a customer would be always online.
But I’d still rather download a game straight from the developer or publisher without an additional middleman. Privacy aside, the cost of that rent seeking from Steam gets passed along to you.
Before Steam you bought a physical disc and it didn’t matter that you technically only purchased a license, the disc was yours and nobody was coming to your house to take it away if the publisher started fighting with the developer or whatever.
