Minecraft java server

What i want for the new 1.17+update for java-

multiplayer should be easier instead of creating .jar files like Minecraft for you to play with your friends on java NEEDS to be easier can you make a single player world online multiplayer like bedrock purchasing the game servers are a real pace of work but port forwarding is too complicated and some people are having problems like 3rd party software like artenos to run servers but even then its too much  lag it hard trying to play with friends I've looked up 100+tutorials and found NO solution please make java Minecraft run servers through game servers it would help the community of Minecraft and no one will have the trouble of having to do so something like port forwarding at All! and you guys can add a thing like friends where u can join and leave there worlds Kind of like Bedrock edition
