A traditional office provides infrastructure and a special ambiance for professionals.
However, these kinds of spaces are not exactly as accommodative as believed:

• High infrastructural costs (Property leasing and rents)
• High Maintenance costs
• Lack of flexibility in terms of work hours
• Generally noisy with higher distractions
• Higher Politics
• Long Commutes
• Various Overheads

A coffee shop or a café can also be a cozy place to take your laptop to work, surrounded by the aromas of cake and coffee.
However, such places can harm the productivity and concentration of any individual:

• Lack of serious environment
• MLM pitches in public places
• The distraction caused by interviews and other social gatherings

• Security issues

Remote working provides a chance to work at flexible hours, from the comfort of your home.

• Not having a proper workspace but working from bed
• A television near you
• Easy access to the refrigerator
• Distracting decorations or furniture designed just for comfort
