So yes 1500 is terrible. You're closer to someone who doesn't know the rules than you are to 2000.
Yes. I see your point. Perhaps "terrible" is an exaggerated term, but I understand the concept.
If you want to make an "objective" speech about the playing strength, you should refer to the path that goes from 0 to at least the first serious goal, that is, the title of Master, and understand at which point of this path you place yourself. The distance between a 1500 chesscom and a pure novice is much smaller than the abysmal distance between a 1500 and a National Master. Not to mention the sidereal distances between a NM and an IM, and between an IM and a GM.
The truth is that 95% of us are low-level players: beginners, amateurs, decent club players, nothing more in terms of playing strength. Only if we get close to being a master can we consider ourselves really strong, serious players. But only an infinitesimal fraction will become players of that level.
There's nothing offensive about that, it's just acknowledging how long the road is to get to a significant level at chess.
Everything else is subjective.
For example, for me something like 1500 would be satisfying, because I know that I could hardly go further, for several reasons. In this sense, each of us can set his own goal, consider it a milestone, and be satisfied if he reaches it. But this is really subjective.
1500 is very good if you are an adult who has obligations and restricted free time to play. Don't listen to the elitists here who will tell you it isn't.
The more you learn about chess the more you realise how hard it is. 1500 is terrible if I'm being honest.
So I got a room with 100 people doing a particular sport and you happen to be better then 90 of them at said sport and thats just terrible???????
