1) Maybe to you it is the case, but remember, we witnessed the evolution from spheres with simple texture and collision that only spawned a white circle and a few particles to high resolution planets with atmosphere and collisions creating real impacts with actual effects and particles that weren't just white dots anymore so, of course it has been improved a lot since the beginning of the alpha, but nothing compared to the "old" universe sandbox² that is already available.
2) Yes, maybe you have to wait longer, but in the meantime, some alpha testers have put some contents on these very forums : videos, screenshots, etc. We "only" had what the devs found time to upload before D-Day (which was still very nice as they were our only source of content). Plus, you only have to wait longer so that you can actually test the game properly, without having to worry too much about horrible crashes and game-breaking bugs (of course it will be your job to test for these, but still, having a non-crashing version will help you a lot).
3) This argument just doesn't make any sense to me as this is entirely subjective.
4) Waiting for something is hard, and this is something I cannot argue with. However, instead of just posting "We are waiting" messages on the forum that will remind you that you are waiting, try forgetting about it for now and do something else, play other videogames or even read the forum, if you really want to be prepared, as you will then be able to distinguish some already reported bugs from new ones you may encounter during your testing. It is a real piece of advice, as it is the way I manage to wait for such awesome things
Now, I won't lie, I don't really like these kind of topics, but you at least had the decency to try to find 4 plausible arguments
