One issue is that good quality education isn’t linear in cost. A school with 5 students may have lower overhead but will lack amenities that enable better learning, eg athletic infrastructure, libraries, etc. We provide public versions of those things, but then we’re back to funding parts of the education system with public levies. Furthermore there are some economies of scale that a public system enables, particularly around equitable access. For instance, I read somewhere that the postal service loses money delivering to remote areas. But given their mandate to serve all Americans, those in remote areas have access to a postal service. A private model would not likely serve those people well, if at all.

The most important thing for young student success is small class size. These concerns you have are more applicable for older students but I’m sure there’s ways to mitigate them.

Small class size helps but you still need a good teacher.
