A couple of reasons.  First, after pouring and leveling the epoxy, I assume that I will probably completely sand through the finish in a fairly large area around it.  I have had problems in the past repairing polyurethane finishes without taking the entire surface down to bare wood before reapplying.  I just have not had good luck blending in areas where I had to sand completely through the finish.   Since I originally posted the question,  he also asked if we could sculpt the ends to make them look more natural.  Right now they are square and we will probably use an angle grinder to sculpt them a little or at least ease the edge.   

The other reason is that the current finish was not applied very well.  The pores in the wood are fairly large he asked if we can make the finish look better.  If I do end up completely stripping the finish, I will probably use a clear grain filler to get a smoother surface before applying the top coat.  

The reason I considered a hard wax finish is that it sounds like it will be less work getting a nice looking finish.  After watching a bunch of different comparisons, it seems that the hard wax finish may not be as durable as my friends probably want to so I will probably just to with whatever finish I determine it actually has.  

The table was delivered yesterday so I will start working on it today.  Hopefully, I will not destroy their new $2000 table.  😮
