a lot of oil comes from the persian gulf. that is hard to get out otherwise. saudi arabia has a pipeline to their westcoast, but that wouldn't meet the demand.

the strait of hormuz is a major choke point in oil trade. unfortunately oil is stil a key ressource for everything. ...

Something like 20% of the world's oil is produced on the other side of Hormuz.

The Persian Gulf is where most of the oil is. The only way in or out of the Persian Gulf is through the strait.

The Encyclopedia Britannica has a great article covering this exact question:

https://www.britannica.com/place/Strait-of-Hormuz

Long story short, the strait is not just the only access point to Kuwait, but also a chokepoint to almost all of Iran, Iraq, Qatar, Saudi Arabia, the UAE and so on.

There is of course the Red Sea, that too allows sea access to some of the countries mentioned above, but that features its own chokepoint strait, the Bab el-Mandeb Strait. That strait is already a conflict zone because of the Houthi conflict. It's also closer to Israel, and it's partly under Iran's control too.

And there's too little infrastructure on that side to divert enough oil from the countries in question compared to the Hormuz side.

So the important thing to remember is the sheer quantity of oil that needs to be moved and where it needs to be moved to. The Strait of Hormuz in 2024 had 20 million barrels of oil passing through it daily. That's 840,000,000 gallons or 3,160,000 cubic meters, or ~1300 Olympic swimming pools each day that need to be moved. It also mostly is going to end up getting moved across oceans to be delivered to the people who need it

Moving that much liquid by means other than boats is very difficult. Building pipelines that can move that much liquid is difficult and prone to problems. Especially considering the very harsh climate surrounding the area and even if you do have a pipeline it's likely still going to end up in a ship because it has to cross an ocean anyway. Moving it by truck is almost logistically impossible, and trains have more problems than pipelines

In order to have the ships big enough to move that liquid you need ports that are deep enough AND already have the infrastructure to handle ships of that size, of which all are already in the Strait. It also made sense because a lot of oil producing countries were in this area so having lots of ships in the area built efficiency

So a whole bunch of confounding factors led to the Strait being the optimal place to move a lot of oil by ship (which the oil needed to go into anyway), however a natural choke point makes this a strategic position for countries in the area. Oil ships are slow, easy targets, and most countries could pretty cheaply take them out. Which adds to the tension in the region

This Wendover Productions video does a good job explaining why so much oil had to go through the Strait

No, there is no other way for ships to get out of the Persian Gulf.
