eVoting needs strong encryption and trust-chain setup. we have done these things for content protection and payments with hardware level security. this is a solvable problem, especially with emergence of block-chain it can be made much more secure. the problem is, as you've pointed out, cost. my somewhat cynical conclusion is that its being left weak intentionally either to save money or plain old incompetence as there is not much openness/competition in govt contracting process. if we ever are to wholeheartedly accept this there has to be complete transparency in the process. at a policy level this is absolute must is we want to converge to a stable long-term solution.
