The visa requirements and renewals are a pain, but surely shouldn't be the main reason for leaving? Get an Elite Visa if you have the money. As for the TM30 and 90-Day Report, you can just skip that nonsense if you wish, and pay a fine once per year or so. You won't be thrown in jail or denied renewal, it's merely a fine (around 2000b). Not bad for saving 3-4 trips to immigration.
And yes, the Thai government is....a joke. But is it really that much worse than anywhere else? Especially other developing nations? I think we're nearing the end of the COVID-19 nonsense restrictions, after that things should get easier.
What is it that you're looking for? I agree that Thailand simply isn't as much fun as it was 10 years ago, sadly. But it's not only Thailand that has changed, the entire world has changed. Everywhere you go people will mainly be staring at their phones, that's all. What will actually be different in Mexico or Ecuador? Thailand still offers the same nice weather, friendly people (in general), safety, good healthcare, decent infrastructure, overall value for money and some of the fun factor it did 10 years ago.
Thailand is a very safe country where you can walk the streets at night completely drunk and probably nothing bad will happen to you. You can forget your keys in the motorcycle ignition for a day and the bike will still be there. You can drive around the country into the smallest most remote villages and not be murdered because you didn't stumble into a cocaine lab run by cartels.
