Voter Registration in Harris County

So I was on the Harris county Tax office site and I see all the options to register involve mailing in the form.

No electronic method is offered whatsover besides the option to prepopulate the form online and then print it- then mail it (at your own cost, I assume).

With most offices that offer these forms closed- I was just wondering why no one has complained about this possible voter disenfranchisement ( most states I know offer online registration). So one can get a prepaid postage ballot in the mail but one cannot get a prepaid voter reg form in the mail, doesn't make sense.

So at this point with the offices closed:

– one needs to have printer access

-one needs to get an envelope and postage to mail in their form

I know some might say this is not complex..but whats the difference with the voter ID requirement concerns?
