Technology has been solving problems people don’t have since… Always. No one had a problem listening to music from an 8 track tape, but that technology still died and we moved on. The truth is that an increasing majority of consumers either don’t care or even prefer wireless headphones. If you consider not having a headphone jack a deal breaker, then you’re not the market most phone manufacturers are after. Sorry to break it to you. Good news though, there are still several smartphone models that have a headphone jack. Buy one of those. Or get whatever phone you want and get a $5 adapter. Or just sit on the internet seething every time a new phone comes out without an increasingly niche feature. Up to you.
