The settlers never should have been there in the first place. It isn't their land and never was. They arrived touting violence and have not ceased. A two state solution validates their self professed "right to the land" and allows for eventual further expansion of the settler colonial state some time in the future should we not keep constant surveillance and management on the proposed Israeli state.

In addition, a single state solution does not necessarily require the forceful expulsion of every settler. It is not inherently violent or oppressive either. In apartheid South Africa many settlers left of their own volition once their privileged status had dissolved.
