Not how the terms slavery and taxation are usually defined no.
If you choose to reduce them to such a level you ignore all their differences and focus on some carefully termed similarities you could make the case they're the same for that specific definition I suppose.
Anyone comparing normal adulthood stuff to slavery needs to spend some time reading some history books.
Anyone who actually read some history books would know slavery was considered "normal stuff" until it wasn't.
So, no answer?
No we can't use such strong words here, theft is more appropriate
