You aren't going to be able to cut 1/2" thick wood with anything for $25,000. Can you force it to happen? Sure, is it something that makes sense to do? No. It's the wrong tool for the job and depending on the type of wood, you might never get through it, or if you do, it'll be a pile of charred mess when you are done with it.
3D engraving into wood is an art and it's VERY slow.
In my opinion, your expectations are way off on what you think a laser can do, and do at a reasonable rate.
I also think your expectation of getting a Fusion M2, or a Trotec with the exhaust and a rotary for under $25,000 is off too.
To get to that price point, with all the options included, you need to step down on models quite a bit.
