I would like to agree, but sending an email that bounces will negatively impact your email reputation and thus your deliverability. I work at a large web company. We ran a test around removing email validation and we had about 20% of users typo their emails when signing up. Simple things like not putting the period before com like "john@gmailcom". It resulted in customers basically creating accounts they couldn't get back to which was a bad user experience and loss of revenue for us. Based on our testing, email validation mostly served to prevent these basic typos.
