Eh... get protection plan, or trade up every year for big discount on the next flagship. Or with AT&T plans you are getting a "free" phone fairly often if you don't intend to leave the carrier for a few years (most people wont). The parent comment you replied to makes some assumptions that you have to spend full price all at once every year which is false. Also, there's almost always a deep discount on Pixel phones around most holidays.
And if you truly are ultra budget $300 phone guy then sure this doesn't apply to you.
