Many users have their own personal macros that can make worksheets visible.

If you want to make it a little more difficult, then when you protect the
workbook:

Tools|Protection|protect workbook
make sure you check that Structure checkbox.

But there is code that is freely available that can remove the worksheet
protection and workbook protection in a matter of moments.

The VBA project protection won't even come into play for this.

And protecting a worksheet doesn't affect the visibility of that worksheet.

The biggest difference is whether the user can see (and show) the

Format|sheet|Unhide dialog

If I have Very Hidden sheets, and protect sheet, workbook and VBA project
with password, and someone unprotect sheet, he has to unprotect also VBA
project so that he can see sheets?
