If interest rates go up to 6%, you are still losing a lot of buying power in a 30-year treasury paying <3%, even if you hold it to term.
30 years of getting 3% on your principle instead of 6% is a massive hit.
Inflation is very likely to eat the people buying these bonds alive.
Unless you think the government will be restrained in their printing of money

If you stay away from bond funds, rising interest rates are great as they allow you to increase your growth and income, if you're a buy & hold bond investor.
