>Do you just not like to travel?

No. I travel extensively. But I keep my travel budget entirely separate from my emergency fund. I only use my emergency fund for emergencies. That's why I have an emergency fund.

>plan to buy a house in 2030 based on my projections. We’d be paying cash. Why would we need to dial back retirement savings?

If you think you'll be able to save enough cash to purchase a home with cash in 7 years and continue to save 25+% of your income for retirement, then you don't need to dial back. However, most people intend to spend a lot more than you apparently are intending to spend on their home.
