I once read an article in Fine Woodworking, explaining by a master woodworker how he can do his work without a table saw. He uses a bandsaw for most of his work.
So, I think a table saw is not a must, although I agree it can do many things faster.
As a hobbyist, I too feel uncomfortable with my table saw and, after I got the tracksaw, I always think a way not to use the table saw.
Yes, it may need few more extra work, but we are not working in a production workshop. It is a part of fun to learn new tricks and master it.
Even if the risk is small, I don't want any injury from my woodworking. In addition, many hobbyists, including me, are not obtaining a proper safety training either.
In the Festool guide by Brice Burrell (The Festool MFS mouli-Routing Template System) and Jerry Work (Getting the Most out of the Festool Multifunction Table), you can find almost all operations, including the narrow rip, can be done by a track saw and a MFT. I especially like MFS400 that can complement the MFT for enhanced accuracy and narrow rip.
Now I seldom see myself using the table saw. Mine is a small table saw and there is no need to get rid of, but if your space is limited, I do understand the dilemma.
