Sure you can. The Roth is just another way the government and Wall Street can get control of some of your wealth. The Roth has limits where other financial instruments do not, like cash value whole life insurance. You can only contribute $5,500 a year to a Roth if you make less than $181,000 a year if you’re married and less than $114,000 if you are single.
The government and Wall Street are in the business of confiscating your wealth from you and diverting it towards their coffers. The more you defer, postpone and separate yourself from your income, the more fees and commissions Wall Street gets to collect.
