Bad actors can buy one.
What does it cost to buy hundreds? It’s a great deterrent to bad actors creating many accounts.
I really, really, really dislike using my phone number to verify. Like so much so it kept me off signal until about 6 months ago.
I get it. I don’t like it, but I get the compromise until they can develop a better mechanism

You could run a network like signal, and either charge a small amount of money per message, or a larger amount of money to register with the network.
Hell you could do the WhatsApp model, charge a dollar for new users, the pay for the registration verification. The same thing.
You just need some mechanism to add friction for mass spamming, be that money time or complexity.
