Could I be arrested for not attending a hearing when my only notification of a hearing was by the plantiff and there was no mention that my must atten

I attended a hearing for a Plaintiffs motion of summary judgement. Judge ruled in plantiffs favor to that I was not surprised. But I did ask why the Courts did not notify me of the hearing? Judge said his office is too busy the planitiff does that. I said this isn't right, why should anyone be obligated to open any mail, read comprehend and act on it unless it came from Government? Judge said if I didn't show up he would have issued a warrent for my arrest. So by the Judges logic this could apply to any citizen that all mail must be read and complied with no matter who sent it. And who could verify the person actually received when no signature is called for it was mailed to me in the regular first class mail. Next I'm told I have to attend a meeting when I have to tell them about all my assets or be arrested. I feel like I'm getting bullied because I can't afford counsel. How can American citizens be compelled to attend any hearing by a private firm and not even mention I need to?
